Applications<\/h2>\n<p>The Fluke Calibration 9172 is designed for applications requiring excellent temperature stability, low thermal gradients and reproducible calibration conditions.<\/p>\n<p>Accurate temperature measurements are essential in pharmaceutical production, laboratory testing, industrial manufacturing and process control.<\/p>\n<p>Temperature sensors must be calibrated regularly to maintain reliable measurement results.<\/p>\n<p>The Fluke Calibration 9172 provides a controlled temperature environment for comparison calibration.<\/p>\n<p>Its temperature range from +35 \u00b0C to +425 \u00b0C covers numerous industrial and laboratory applications.<\/p>\n<p>The instrument is particularly suitable for calibrating platinum resistance thermometers and industrial temperature sensors.<\/p>\n<p>Typical applications include calibration laboratories, pharmaceutical production, temperature controlled manufacturing processes and quality assurance departments.<\/p>\n<p>For demanding calibration applications, a calibrated external reference thermometer can be used to determine the actual temperature inside the calibration insert.<\/p>\n<p>This allows the device under test to be compared directly with a traceable reference temperature.<\/p>\n<h2>Temperature Range from +35 \u00b0C to +425 \u00b0C<\/h2>\n<p>The <strong>Fluke Calibration 9172<\/strong> provides a temperature range of:<\/p>\n<p><strong>+35 \u00b0C to +425 \u00b0C<\/strong><\/p>\n<p>The specified range applies at an ambient temperature of 23 \u00b0C.<\/p>\n<p>This makes the instrument suitable for calibration applications requiring temperatures above ambient conditions.<\/p>\n<p>The integrated heating system enables the instrument to generate stable temperatures throughout its operating range.<\/p>\n<p>Typical calibration temperatures may include 50 \u00b0C, 100 \u00b0C, 150 \u00b0C, 200 \u00b0C, 300 \u00b0C and 400 \u00b0C.<\/p>\n<p>The appropriate calibration points depend on the operating range and accuracy requirements of the temperature sensor under test.<\/p>\n<h2>Exceptional Temperature Stability<\/h2>\n<p>Temperature stability is one of the most important characteristics of a precision temperature calibrator.<\/p>\n<p>The Fluke Calibration 9172 provides:<\/p>\n<p><strong>\u00b10.005 \u00b0C from 35 \u00b0C to 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.008 \u00b0C from 100 \u00b0C to 225 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.01 \u00b0C from 225 \u00b0C to 425 \u00b0C<\/strong><\/p>\n<p>These values demonstrate the excellent temperature control performance of the instrument.<\/p>\n<p>Temperature stability describes fluctuations of the calibration source temperature over time under defined operating conditions.<\/p>\n<p>Excellent stability is particularly important when calibrating precision resistance thermometers.<\/p>\n<p>It helps reduce measurement uncertainty contributions caused by temporal temperature fluctuations.<\/p>\n<p>However, temperature stability must not be confused with the accuracy of the internal temperature indication or the expanded measurement uncertainty of a calibration.<\/p>\n<h2>Accurate Temperature Indication<\/h2>\n<p>The Fluke Calibration 9172 features a calibrated temperature display.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.1 \u00b0C from 35 \u00b0C to 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.15 \u00b0C from 100 \u00b0C to 225 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.2 \u00b0C from 225 \u00b0C to 425 \u00b0C<\/strong><\/p>\n<p>These specifications describe the accuracy of the internal temperature indication.<\/p>\n<p>For applications where this accuracy is sufficient, the internal temperature indication can be used as the reference.<\/p>\n<p>For demanding comparison calibration, an external calibrated reference thermometer is recommended.<\/p>\n<p>The reference thermometer measures the temperature at the calibration position.<\/p>\n<p>The device under test can then be compared with the reference temperature.<\/p>\n<p>The achievable measurement uncertainty depends on the reference thermometer, temperature uniformity, stability and calibration procedure.<\/p>\n<h2>Excellent Axial Temperature Uniformity<\/h2>\n<p>The Fluke Calibration 9172 provides well-characterized axial temperature uniformity.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.05 \u00b0C from 35 \u00b0C to 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.1 \u00b0C from 100 \u00b0C to 225 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.2 \u00b0C from 225 \u00b0C to 425 \u00b0C<\/strong><\/p>\n<p>These values describe the temperature distribution within a 60 mm axial zone.<\/p>\n<p>Axial uniformity describes temperature differences along the vertical direction of the calibration well.<\/p>\n<p>Temperature gradients can influence calibration results when sensors have different immersion depths or sensing element positions.<\/p>\n<p>The Fluke Calibration 9172 is designed to minimize these effects.<\/p>\n<p>For accurate comparison calibration, the reference thermometer and device under test should be positioned at suitable and comparable immersion depths.<\/p>\n<h2>Excellent Radial Temperature Uniformity<\/h2>\n<p>The Fluke Calibration 9172 provides excellent radial temperature uniformity.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.01 \u00b0C from 35 \u00b0C to 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.02 \u00b0C from 100 \u00b0C to 225 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.025 \u00b0C from 225 \u00b0C to 425 \u00b0C<\/strong><\/p>\n<p>Radial uniformity describes temperature differences between measurement positions within the calibration insert.<\/p>\n<p>Good radial uniformity is particularly important when several temperature sensors are calibrated simultaneously.<\/p>\n<p>It helps ensure that the reference thermometer and devices under test are exposed to similar temperatures.<\/p>\n<p>The actual temperature distribution depends on the insert configuration, probe dimensions and thermal loading.<\/p>\n<h2>Low Temperature Loading Effect<\/h2>\n<p>The Fluke Calibration 9172 provides a low temperature loading effect.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.01 \u00b0C throughout the operating range<\/strong><\/p>\n<p>This specification applies under defined conditions using one 6.35 mm reference thermometer and three additional 6.35 mm probes.<\/p>\n<p>The loading effect describes temperature changes caused by inserting additional sensors into the calibration block.<\/p>\n<p>Low loading effects are particularly important during comparison calibration.<\/p>\n<p>They help maintain stable temperature conditions when several sensors are inserted simultaneously.<\/p>\n<h2>Temperature Hysteresis<\/h2>\n<p>The Fluke Calibration 9172 has a specified temperature hysteresis of:<\/p>\n<p><strong>0.04 \u00b0C<\/strong><\/p>\n<p>Temperature hysteresis describes differences in the temperature indication depending on whether a calibration temperature is approached from a higher or lower temperature.<\/p>\n<p>This effect can contribute to the measurement uncertainty.<\/p>\n<p>The Fluke Calibration 9172 is designed to provide reproducible calibration conditions during heating and cooling cycles.<\/p>\n<h2>Calibration Well Depth of 203 mm<\/h2>\n<p>One of the most important advantages of the Fluke Calibration 9172 is its deep calibration well.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>203 mm<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>8 inches<\/strong><\/p>\n<p>Sufficient immersion depth is particularly important when calibrating resistance thermometers.<\/p>\n<p>Heat conduction along the thermometer stem can cause differences between the sensing element temperature and the actual temperature of the calibration block.<\/p>\n<p>The deep calibration well helps reduce these effects.<\/p>\n<p>It is particularly beneficial when calibrating longer industrial temperature sensors.<\/p>\n<p>The required immersion depth depends on the sensor construction, diameter, sensing element length and calibration temperature.<\/p>\n<h2>Temperature Resolution of 0.001 \u00b0C<\/h2>\n<p>The Fluke Calibration 9172 provides a temperature display resolution of:<\/p>\n<p><strong>0.001 \u00b0C<\/strong><\/p>\n<p>This corresponds to one millikelvin.<\/p>\n<p>The fine display resolution allows small temperature changes to be observed.<\/p>\n<p>It is particularly useful when monitoring temperature stability and performing precision comparison measurements.<\/p>\n<p>Display resolution must not be confused with temperature accuracy or measurement uncertainty.<\/p>\n<h2>Heating and Cooling Performance<\/h2>\n<p>The Fluke Calibration 9172 provides efficient heating performance.<\/p>\n<p>The manufacturer specifies the following typical times:<\/p>\n<p><strong>Heating from 35 \u00b0C to 425 \u00b0C: 27 minutes<\/strong><\/p>\n<p><strong>Cooling from 425 \u00b0C to 100 \u00b0C: 100 minutes<\/strong><\/p>\n<p><strong>Cooling from 425 \u00b0C to 35 \u00b0C: 220 minutes<\/strong><\/p>\n<p>These characteristics support calibration procedures involving multiple temperature points.<\/p>\n<p>The heating time of approximately 27 minutes allows the instrument to reach its maximum operating temperature relatively quickly.<\/p>\n<p>Cooling from high temperatures requires considerably more time.<\/p>\n<p>Actual heating and cooling times depend on operating conditions and thermal loading.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The Fluke Calibration 9172 uses interchangeable brass calibration inserts.<\/p>\n<p>Different insert configurations are available for temperature sensors with different diameters.<\/p>\n<p>The manufacturer offers six standard configurations.<\/p>\n<p><strong>Insert A:<\/strong> Mixed imperial calibration openings.<\/p>\n<p><strong>Insert B:<\/strong> Imperial comparison openings.<\/p>\n<p><strong>Insert C:<\/strong> Six openings with a diameter of 6.35 mm.<\/p>\n<p><strong>Insert D:<\/strong> Metric comparison openings.<\/p>\n<p><strong>Insert E:<\/strong> Mixed metric openings with an additional 6.35 mm reference opening.<\/p>\n<p><strong>Insert F:<\/strong> Metric comparison openings with an additional 6.35 mm reference opening.<\/p>\n<p>A blank insert is also available for customized applications.<\/p>\n<p>The appropriate insert should be selected according to the dimensions of the reference thermometer and the devices under test.<\/p>\n<p>A suitable fit between the sensor and insert helps improve thermal contact and reduce measurement uncertainty.<\/p>\n<h2>Optional Integrated Reference Thermometer Input<\/h2>\n<p>The Fluke Calibration 9172 is available with an optional integrated reference thermometer input.<\/p>\n<p>These versions are identified by the additional <strong>R<\/strong> in the model designation.<\/p>\n<p>For example:<\/p>\n<p><strong>Fluke Calibration 9172-A-R<\/strong><\/p>\n<p>The integrated reference input supports compatible platinum resistance thermometers.<\/p>\n<p>It allows temperature measurements using ITS-90 and Callendar Van Dusen coefficients.<\/p>\n<p>The manufacturer specifies the following reference readout accuracy values for 25 \u03a9 and 100 \u03a9 PRTs:<\/p>\n<p><strong>\u00b10.007 \u00b0C at 0 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.011 \u00b0C at 155 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.013 \u00b0C at 225 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.019 \u00b0C at 425 \u00b0C<\/strong><\/p>\n<p>These values describe the accuracy of the integrated reference thermometer readout.<\/p>\n<p>They do not include the uncertainty of the connected reference thermometer.<\/p>\n<p>The total measurement uncertainty depends on the reference thermometer, readout and calibration conditions.<\/p>\n<h2>Platinum Resistance Thermometer Calibration<\/h2>\n<p>The Fluke Calibration 9172 is particularly suitable for calibrating platinum resistance thermometers.<\/p>\n<p>Typical applications include Pt100 sensors, precision platinum resistance thermometers and compatible reference thermometers.<\/p>\n<p>The sensor under test is inserted into a suitable calibration opening.<\/p>\n<p>A calibrated reference thermometer is positioned in another opening.<\/p>\n<p>After thermal stabilization, the temperature indications are compared.<\/p>\n<p>The indication error can be calculated as:<\/p>\n<p><strong>\u0394T = T_DUT \u2212 T_REF<\/strong><\/p>\n<p>Where:<\/p>\n<p><strong>\u0394T<\/strong> is the temperature indication error.<\/p>\n<p><strong>T_DUT<\/strong> is the temperature indicated by the device under test.<\/p>\n<p><strong>T_REF<\/strong> is the reference temperature.<\/p>\n<p>The measurement uncertainty depends on the reference thermometer, thermal uniformity, stability, loading effect and immersion depth.<\/p>\n<h2>Automated Calibration Procedures<\/h2>\n<p>The Fluke Calibration 9172 includes programmable calibration functions.<\/p>\n<p>The instrument supports:<\/p>\n<p><strong>Four programmable calibration procedures<\/strong><\/p>\n<p>Each procedure can contain up to:<\/p>\n<p><strong>Eight temperature setpoints<\/strong><\/p>\n<p>Users can configure temperature setpoints, ramp times and hold times.<\/p>\n<p>This helps simplify repeated calibration procedures.<\/p>\n<p>The instrument can automatically move between selected temperature setpoints without requiring continuous manual adjustment.<\/p>\n<p>These functions are particularly useful when calibrating temperature sensors at several temperatures.<\/p>\n<h2>Automatic Temperature Switch Testing<\/h2>\n<p>The Fluke Calibration 9172 supports automatic temperature switch testing.<\/p>\n<p>Temperature switches are widely used in industrial process control and safety systems.<\/p>\n<p>The automatic test function simplifies the determination of switching temperatures and switching hysteresis.<\/p>\n<p>This helps improve efficiency during routine maintenance and calibration procedures.<\/p>\n<h2>RS232 Communication and Automation<\/h2>\n<p>The Fluke Calibration 9172 features an integrated RS232 communication interface.<\/p>\n<p>This allows the instrument to communicate with a computer or compatible calibration software.<\/p>\n<p>The instrument is compatible with Fluke Calibration MET\/TEMP II software.<\/p>\n<p>The interface supports remote operation and integration into automated calibration procedures.<\/p>\n<p>Automated calibration can help reduce manual work and improve the consistency of repeated measurements.<\/p>\n<p>The instrument can also be operated independently without a computer.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>Fluke Calibration 9172<\/th>\n<\/tr>\n<tr>\n<td>Manufacturer<\/td>\n<td>Fluke
