generators<\/li>\n<li>Suitable as a replacement for mechanical pressure gauges<\/li>\n<li>Designed for laboratory and field use<\/li>\n<\/ul>\n<h2>\u00b10.2% of Reading Accuracy<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> provides an accuracy specification based primarily on the measured value rather than exclusively on the full-scale pressure range.<\/p>\n<p>For pressures from:<\/p>\n<p><strong>20% to 110% of range<\/strong><\/p>\n<p>the m1 specification is:<\/p>\n<p><strong>\u00b10.2% of reading<\/strong>.<\/p>\n<p>From:<\/p>\n<p><strong>0% to 20% of range<\/strong><\/p>\n<p>the specification is:<\/p>\n<p><strong>\u00b10.04% of full scale<\/strong>.<\/p>\n<p>This combination allows the instrument to maintain useful measurement performance over a broad pressure range.<\/p>\n<p>The accuracy specification includes the effects of:<\/p>\n<ul>\n<li>Linearity<\/li>\n<li>Hysteresis<\/li>\n<li>Repeatability<\/li>\n<li>Temperature<\/li>\n<li>Stability<\/li>\n<\/ul>\n<p>over the recommended two-year calibration interval.<\/p>\n<h2>One Digital Gauge Can Replace Multiple Mechanical Gauges<\/h2>\n<p>A conventional mechanical pressure gauge is frequently specified as a percentage of its full-scale value.<\/p>\n<p>As the applied pressure decreases, the relative uncertainty of such a gauge therefore increases.<\/p>\n<p>The <strong>AMETEK Crystal m1<\/strong> uses a reading-based accuracy specification over most of its range.<\/p>\n<p>AMETEK states that one wide-range m1 can replace up to:<\/p>\n<p><strong>five 0.25% mechanical pressure gauges<\/strong>.<\/p>\n<p>This can reduce the number of pressure gauges required for routine service and maintenance applications.<\/p>\n<h2>Pressure Ranges up to 700 bar<\/h2>\n<p>The AMETEK Crystal m1 is available in multiple pressure ranges.<\/p>\n<p>Metric versions include ranges such as:<\/p>\n<ul>\n<li>2 bar<\/li>\n<li>10 bar<\/li>\n<li>20 bar<\/li>\n<li>100 bar<\/li>\n<li>200 bar<\/li>\n<li>700 bar<\/li>\n<\/ul>\n<p>Corresponding psi versions include:<\/p>\n<ul>\n<li>30 psi<\/li>\n<li>100 psi<\/li>\n<li>300 psi<\/li>\n<li>1,000 psi<\/li>\n<li>3,000 psi<\/li>\n<li>10,000 psi<\/li>\n<\/ul>\n<p>MPa versions are also available.<\/p>\n<p>This broad range selection makes the m1 suitable for applications from low pneumatic pressures to high hydraulic pressures.<\/p>\n<h2>Vacuum Measurement<\/h2>\n<p>All <strong>AMETEK Crystal m1<\/strong> models can indicate vacuum.<\/p>\n<p>Specified vacuum performance applies to selected lower-pressure models.<\/p>\n<p>For vacuum measurement, AMETEK specifies:<\/p>\n<p><strong>\u00b10.25% of full scale<\/strong><\/p>\n<p>with the corresponding vacuum full scale defined according to the selected engineering unit.<\/p>\n<p>For applications involving continuous high vacuum, a dedicated vacuum-capable pressure instrument should be considered according to the manufacturer&#8217;s recommendations.<\/p>\n<h2>Wide Operating Temperature Range<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> is designed to maintain its specified measurement performance over an operating temperature range of:<\/p>\n<p><strong>-10 \u00b0C to +50 \u00b0C<\/strong>.<\/p>\n<p>AMETEK specifies no additional accuracy change across this operating temperature range when the instrument is correctly zeroed.<\/p>\n<p>This is particularly useful for field applications.<\/p>\n<p>A digital pressure gauge may be calibrated under controlled laboratory conditions but subsequently used outdoors or in industrial environments with significantly different ambient temperatures.<\/p>\n<p>The m1 is designed to minimize the effect of these temperature changes on pressure measurement accuracy.<\/p>\n<h2>Rugged Industrial Design<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> is designed for everyday industrial use.<\/p>\n<p>According to AMETEK, the instrument is engineered so that its measurement accuracy is resistant to common influences including:<\/p>\n<ul>\n<li>Mechanical shock<\/li>\n<li>Overpressure<\/li>\n<li>Vibration<\/li>\n<li>Temperature changes<\/li>\n<li>Rapid pressure changes<\/li>\n<\/ul>\n<p>A protective elastomeric boot is supplied with the instrument.<\/p>\n<p>This helps protect the gauge against the mechanical stresses commonly encountered during field service and maintenance work.<\/p>\n<h2>Large Backlit Display<\/h2>\n<p>The AMETEK Crystal m1 uses a:<\/p>\n<p><strong>5-digit LCD<\/strong>.<\/p>\n<p>The numerical characters are approximately:<\/p>\n<p><strong>16.8 mm \/ 0.66 inches high<\/strong>.<\/p>\n<p>The large characters make pressure values easy to read from a practical working distance.<\/p>\n<p>A bright backlight improves readability in poorly illuminated environments.<\/p>\n<p>The LCD is also designed to remain readable in sunlight.<\/p>\n<h2>Four Readings per Second<\/h2>\n<p>The standard display update rate is:<\/p>\n<p><strong>4 readings per second<\/strong>.<\/p>\n<p>This provides responsive pressure indication during adjustment of pneumatic and hydraulic pressure sources.<\/p>\n<p>The fast display response is particularly useful when approaching a required pressure calibration point.<\/p>\n<h2>Long Battery Life<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> operates from:<\/p>\n<p><strong>2 \u00d7 AA alkaline batteries<\/strong>.<\/p>\n<p>Typical continuous operation at the standard measurement rate is approximately:<\/p>\n<p><strong>900 hours<\/strong>.<\/p>\n<p>The instrument also provides selectable extended battery modes.<\/p>\n<p>Depending on the selected measurement interval, operating times can be extended substantially.<\/p>\n<p>For example, slower measurement intervals can provide operating times of several thousand hours.<\/p>\n<p>At the longest selectable intervals, AMETEK specifies battery life approaching:<\/p>\n<p><strong>30,000 hours<\/strong>.<\/p>\n<p>This corresponds to approximately three years of operation under suitable usage conditions.<\/p>\n<h2>Two-Year Recommended Calibration Interval<\/h2>\n<p>AMETEK specifies a recommended calibration interval of:<\/p>\n<p><strong>2 years<\/strong><\/p>\n<p>for the Crystal m1.<\/p>\n<p>The pressure accuracy specification includes stability over this period.<\/p>\n<p>A longer calibration interval can reduce maintenance effort and operating costs compared with instruments requiring annual calibration, provided that the calibration interval is appropriate for the user&#8217;s quality system, application and historical stability data.<\/p>\n<h2>CPF Pressure Connection<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> uses the Crystal:<\/p>\n<p><strong>CPF \u2013 Crystal Pressure Fitting<\/strong><\/p>\n<p>system.<\/p>\n<p>The standard pressure connection incorporates a:<\/p>\n<p><strong>7\/16-20 MP CPF port<\/strong>.<\/p>\n<p>One advantage of this design is that normal connection wear can be transferred to a replaceable adapter rather than directly affecting the pressure gauge body.<\/p>\n<p>This can extend the practical service life of the instrument.<\/p>\n<h2>Replaceable Pressure Adapter<\/h2>\n<p>AMETEK specifically highlights the replaceable CPF adapter as a durability feature of the m1.<\/p>\n<p>Pressure gauges used regularly in calibration and maintenance applications may be connected and disconnected hundreds or thousands of times.<\/p>\n<p>Thread wear can therefore become an important long-term consideration.<\/p>\n<p>With the m1, the adapter can be replaced when required rather than replacing the complete pressure gauge.<\/p>\n<h2>Optional BSP Connection<\/h2>\n<p>For applications using European pressure fittings, the m1 is available with an optional:<\/p>\n<p><strong>G 1\/4 B parallel pressure fitting<\/strong>.<\/p>\n<p>This makes the gauge easier to integrate into existing European pneumatic and hydraulic systems.<\/p>\n<p>A corresponding copper sealing washer is also available.<\/p>\n<h2>Optional M20 \u00d7 1.5 Adapter<\/h2>\n<p>An optional:<\/p>\n<p><strong>M20 \u00d7 1.5 male CPF adapter<\/strong><\/p>\n<p>is also available.<\/p>\n<p>This connection is frequently encountered on pressure calibration equipment and industrial pressure instruments.<\/p>\n<p>The adapter system allows the m1 to be configured for different laboratory and field connection standards.<\/p>\n<h2>Pressure Gauge Calibration<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> can be used as a digital pressure indicator in comparison pressure measurement applications.<\/p>\n<p>A typical setup consists of:<\/p>\n<p><strong>Pressure Source \u2192 Reference Gauge + Device Under Test<\/strong><\/p>\n<p>A suitable pneumatic or hydraulic pressure source generates the required test pressure.<\/p>\n<p>The pressure indication can then be compared with the instrument under test.<\/p>\n<p>The suitability of the m1 as a reference should always be evaluated according to the required test uncertainty ratio and the measurement uncertainty of the complete calibration system.<\/p>\n<h2>Pneumatic Pressure Applications<\/h2>\n<p>For lower pressure ranges, the AMETEK Crystal m1 can be combined with pneumatic hand pumps.<\/p>\n<p>AMETEK offers several compatible systems.<\/p>\n<p>Examples include:<\/p>\n<p><strong>T-960<\/strong><\/p>\n<p>for pressures up to approximately:<\/p>\n<p><strong>30 psi \/ 2 bar<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>T-970<\/strong><\/p>\n<p>for pressures up to approximately:<\/p>\n<p><strong>580 psi \/ 40 bar<\/strong>.<\/p>\n<p>Vacuum and pressure applications can be covered using pumps such as the:<\/p>\n<p><strong>T-965<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>T-975<\/strong>.<\/p>\n<p>This creates a portable pressure test system for field service applications.<\/p>\n<h2>Hydraulic Pressure Applications<\/h2>\n<p>For higher pressure ranges, the m1 can be combined with hydraulic pressure pumps.<\/p>\n<p>Compatible AMETEK systems include pressure sources for ranges such as:<\/p>\n<p><strong>3,000 psi \/ 200 bar<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>5,000 psi \/ 350 bar<\/strong>.<\/p>\n<p>For the highest m1 pressure range of:<\/p>\n<p><strong>10,000 psi \/ 700 bar<\/strong><\/p>\n<p>a suitably rated hydraulic pressure source can be used.<\/p>\n<p>This allows the m1 platform to cover both pneumatic and hydraulic pressure measurement applications.<\/p>\n<h2>Complete Pressure Systems<\/h2>\n<p>AMETEK offers the Crystal m1 as part of complete pressure system configurations.<\/p>\n<p>Depending on the selected system, a package can combine:<\/p>\n<ul>\n<li>m1 digital pressure gauge<\/li>\n<li>Pneumatic or hydraulic pressure pump<\/li>\n<li>Pressure fittings<\/li>\n<li>Connection accessories<\/li>\n<li>Carrying case<\/li>\n<\/ul>\n<p>This provides a convenient portable solution for maintenance and pressure testing.<\/p>\n<h2>Protective Boot<\/h2>\n<p>A protective boot is included with the <strong>AMETEK Crystal m1<\/strong>.<\/p>\n<p>The boot is manufactured from a Skydrol-compatible elastomeric material and increases resistance to mechanical shock.<\/p>\n<p>This is particularly useful for portable field applications where instruments are regularly transported and handled.<\/p>\n<h2>Carrying Cases<\/h2>\n<p>Several carrying cases are available for the m1.<\/p>\n<p>These include a compact hard carrying case with protective foam as well as a larger weatherproof hard case.<\/p>\n<p>A suitable carrying case protects the instrument, fittings and accessories during transport between calibration locations.<\/p>\n<h2>Magnetic Hanging Strap<\/h2>\n<p>An optional:<\/p>\n<p><strong>magnetic hanging strap<\/strong><\/p>\n<p>is available for the AMETEK Crystal m1.<\/p>\n<p>This accessory allows the gauge to be positioned on suitable metallic surfaces during field work.<\/p>\n<p>It can be particularly useful when both hands are required to operate a pressure pump or adjust the device under test.<\/p>\n<h2>Pressure Units<\/h2>\n<p>The AMETEK Crystal m1 is available in different engineering-unit configurations.<\/p>\n<p>Depending on model, these include versions based on:<\/p>\n<ul>\n<li>psi<\/li>\n<li>bar<\/li>\n<li>MPa<\/li>\n<li>kgf\/cm\u00b2<\/li>\n<\/ul>\n<p>This allows the gauge to be selected according to the pressure units normally used in the application.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>AMETEK Crystal m1<\/th>\n<\/tr>\n<tr>\n<td>Product type<\/td>\n<td>Digital

Crystal m1 vs. XP2i<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> and Crystal XP2i are both digital pressure gauges, but they address different measurement requirements.<\/p>\n<p>The m1 focuses on:<\/p>\n<ul>\n<li>Economical pressure measurement<\/li>\n<li>\u00b10.2% of reading accuracy<\/li>\n<li>Simple operation<\/li>\n<li>Long battery life<\/li>\n<li>Routine industrial pressure measurement<\/li>\n<li>Replacement of mechanical gauges<\/li>\n<\/ul>\n<p>The XP2i provides higher measurement performance with accuracy options down to:<\/p>\n<p><strong>\u00b10.1% of reading<\/strong><\/p>\n<p>and is available for pressures up to:<\/p>\n<p><strong>15,000 psi<\/strong>.<\/p>\n<p>The XP2i is also available with intrinsic safety approval for hazardous-area pressure measurement.<\/p>\n<p>The appropriate instrument therefore depends on the required measurement uncertainty, pressure range and application environment.<\/p>\n<h2>AMETEK Crystal m1 vs. HPC<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> should also be distinguished from the AMETEK Crystal HPC pressure calibrators.<\/p>\n<p>The:<\/p>\n<p><strong>m1<\/strong><\/p>\n<p>is primarily a:<\/p>\n<p><strong>Digital Pressure Gauge<\/strong>.<\/p>\n<p>The:<\/p>\n<p><strong>HPC<\/strong><\/p>\n<p>is a multifunction:<\/p>\n<p><strong>Handheld Pressure Calibrator<\/strong>.<\/p>\n<p>HPC instruments provide substantially higher measurement performance and additional electrical and temperature calibration functions.<\/p>\n<p>The m1 is therefore particularly suitable when straightforward, reliable digital pressure measurement is required without the additional functionality of a multifunction process calibrator.<\/p>\n<h2>Typical Applications<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> is suitable for:<\/p>\n<ul>\n<li>Digital pressure measurement<\/li>\n<li>Replacement of mechanical pressure gauges<\/li>\n<li>Pressure gauge

Crystal m1?<\/h2>\n<p>The <strong>AMETEK Crystal m1<\/strong> provides a practical combination of accuracy, ruggedness and economy for professional pressure measurement.<\/p>\n<p>Its <strong>\u00b10.2% of reading<\/strong> specification over most of the measurement range allows a single m1 to replace several conventional full-scale-based mechanical pressure gauges.<\/p>\n<p>Available pressure ranges extend up to <strong>10,000 psi \/ 700 bar<\/strong>, enabling applications from low-pressure pneumatic systems through high-pressure hydraulic measurement.<\/p>\n<p>The specified performance is maintained from <strong>-10 \u00b0C to +50 \u00b0C<\/strong>, making the instrument suitable for both laboratory and field environments.<\/p>\n<p>A large backlit display, simple operation and long battery life make the m1 particularly convenient for routine maintenance and pressure testing.<\/p>\n<p>The recommended <strong>2-year calibration interval<\/strong> helps reduce maintenance requirements, while the replaceable CPF pressure adapter protects the gauge itself against connection wear.<\/p>\n<p>Optional G 1\/4 B and M20 \u00d7 1.5 adapters simplify integration into different pressure systems.<\/p>\n<p>Combined with suitable AMETEK pneumatic or hydraulic pressure generation equipment, the Crystal m1 can form part of a complete
