temperature.<\/p>\n<p>Low long-term drift is particularly important for reference thermometers used regularly in calibration laboratories.<\/p>\n<p>It helps maintain reliable measurement performance between calibration intervals.<\/p>\n<p>Actual drift depends on handling, operating conditions, thermal exposure and maintenance.<\/p>\n<p>Regular recalibration remains necessary to verify the performance of the reference thermometer.<\/p>\n<h2>Low Hysteresis<\/h2>\n<p>The Additel AccuMac AM 1730 features low temperature hysteresis.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u22640.005 \u00b0C<\/strong><\/p>\n<p>Hysteresis describes differences in thermometer indication that may occur depending on the previous temperature exposure.<\/p>\n<p>Low hysteresis is particularly important when measurements are performed over a wide temperature range.<\/p>\n<p>It helps improve repeatability when switching between low and high calibration temperatures.<\/p>\n<p>The sensor construction is designed to minimize mechanical stresses in the platinum sensing element.<\/p>\n<h2>Excellent Thermal Shock Resistance<\/h2>\n<p>The Additel AccuMac AM 1730 is designed to withstand demanding thermal conditions.<\/p>\n<p>The manufacturer specifies a thermal shock effect of:<\/p>\n<p><strong>Less than 0.005 \u00b0C<\/strong><\/p>\n<p>This value applies after ten thermal cycles between the minimum and maximum operating temperatures under the specified test conditions.<\/p>\n<p>The sensor design helps reduce measurement changes caused by repeated temperature cycling.<\/p>\n<p>This makes the thermometer suitable for calibration procedures involving frequent temperature changes.<\/p>\n<p>However, appropriate handling and controlled temperature transitions are still recommended to protect the sensor and maintain long-term performance.<\/p>\n<h2>High-Quality Platinum Sensing Element<\/h2>\n<p>The Additel AccuMac AM 1730 uses a specially designed platinum resistance sensing element.<\/p>\n<p>The sensing element is engineered to minimize contamination and mechanical stress.<\/p>\n<p>A dedicated supporting structure and filling material help balance thermal shock resistance, mechanical stability and hysteresis performance.<\/p>\n<p>The sensor meets the relevant ITS-90 criteria for reference thermometers.<\/p>\n<p>This makes the Additel AccuMac AM 1730 suitable for precision temperature measurement using individually calibrated resistance-temperature characteristics.<\/p>\n<p>For accurate temperature calculations, the calibration coefficients supplied with the thermometer should be used in a compatible reference readout.<\/p>\n<h2>Nominal Resistance of 100 \u03a9<\/h2>\n<p>The Additel AccuMac AM 1730 has a nominal resistance of:<\/p>\n<p><strong>100 \u03a9 at 0.01 \u00b0C<\/strong><\/p>\n<p>The specified temperature coefficient is:<\/p>\n<p><strong>0.003925 \u03a9\/\u03a9\/\u00b0C<\/strong><\/p>\n<p>This characteristic differs from the commonly used industrial Pt100 characteristic with a nominal temperature coefficient of approximately 0.00385 \u03a9\/\u03a9\/\u00b0C.<\/p>\n<p>For accurate temperature measurements, the correct sensor characteristic and individual calibration coefficients must be configured in the reference thermometer readout.<\/p>\n<p>Using an incorrect resistance-temperature characteristic can introduce significant measurement errors.<\/p>\n<h2>Four-Wire Resistance Measurement<\/h2>\n<p>The Additel AccuMac AM 1730 uses a four-wire connection.<\/p>\n<p>Four-wire resistance measurement minimizes errors caused by lead resistance.<\/p>\n<p>Two conductors supply the measurement current, while the other two conductors measure the voltage across the sensing element.<\/p>\n<p>This method is essential for high-accuracy resistance thermometry.<\/p>\n<p>The manufacturer specifies measurement currents of:<\/p>\n<p><strong>0.5 mA or 1 mA<\/strong><\/p>\n<p>The appropriate current should be selected according to the measurement application.<\/p>\n<p>The influence of sensor self-heating must be considered when evaluating the measurement uncertainty.<\/p>\n<h2>Robust Inconel Protective Sheath<\/h2>\n<p>The Additel AccuMac AM 1730 features a protective sheath manufactured from Inconel.<\/p>\n<p>Inconel is a nickel-based alloy known for its mechanical strength and resistance to demanding temperature conditions.<\/p>\n<p>The sheath protects the platinum sensing element from mechanical damage and environmental influences.<\/p>\n<p>This construction makes the reference thermometer suitable for professional laboratory and field applications.<\/p>\n<p>The compatibility of the sheath material with the calibration medium should be verified for the intended application.<\/p>\n<h2>Available Probe Configurations<\/h2>\n<p>The Additel AccuMac AM 1730 is available in several configurations.<\/p>\n<h3>AM1730-12<\/h3>\n<p>The AM1730-12 features a straight probe with the following dimensions:<\/p>\n<p><strong>Diameter: 6.35 mm<\/strong><\/p>\n<p><strong>Length: 305 mm<\/strong><\/p>\n<p>This configuration is suitable for laboratory calibration baths and dry block calibrators with sufficient immersion depth.<\/p>\n<h3>AM1730-9<\/h3>\n<p>The AM1730-9 features a smaller probe diameter.<\/p>\n<p><strong>Diameter: 4.775 mm<\/strong><\/p>\n<p><strong>Length: 228.6 mm<\/strong><\/p>\n<p>The smaller diameter can be advantageous when calibrating sensors in narrow wells or inserts.<\/p>\n<h3>AM1730-BEND<\/h3>\n<p>The AM1730-BEND features an angled probe design.<\/p>\n<p>The sheath has a diameter of:<\/p>\n<p><strong>6.35 mm<\/strong><\/p>\n<p>The dimensions

installation space is limited or a straight probe cannot be positioned conveniently.<\/p>\n<h2>Fast Response Time<\/h2>\n<p>The Additel AccuMac AM 1730 provides a fast thermal response.<\/p>\n<p>The manufacturer specifies the following response times:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Configuration<\/th>\n<th>Response Time<\/th>\n<\/tr>\n<tr>\n<td>AM1730-12<\/td>\n<td>9 seconds<\/td>\n<\/tr>\n<tr>\n<td>AM1730-9<\/td>\n<td>6 seconds<\/td>\n<\/tr>\n<tr>\n<td>AM1730-BEND<\/td>\n<td>9 seconds<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The response time refers to 63% of a temperature step change in moving water at a flow velocity of 1 m\/s.<\/p>\n<p>Actual response times depend on the calibration medium, immersion depth and thermal contact.<\/p>\n<p>The smaller diameter of the AM1730-9 provides a faster response under the specified test conditions.<\/p>\n<h2>Suitable for Liquid Calibration Baths<\/h2>\n<p>The Additel AccuMac AM 1730 is particularly suitable for use as a reference thermometer in liquid calibration baths.<\/p>\n<p>Liquid baths provide excellent temperature stability and uniformity when operated correctly.<\/p>\n<p>The reference thermometer measures the bath temperature while the devices under test are compared against it.<\/p>\n<p>This method is commonly used for calibrating industrial resistance thermometers, precision temperature probes and digital thermometers.<\/p>\n<p>The temperature range and compatibility of the calibration liquid must be considered.<\/p>\n<h2>Suitable for Dry Block Calibrators<\/h2>\n<p>The Additel AccuMac AM 1730 can also be used with suitable dry block temperature calibrators.<\/p>\n<p>The reference thermometer is inserted into an appropriate calibration insert.<\/p>\n<p>The temperature of the calibration block is measured directly using the reference thermometer.<\/p>\n<p>The device under test is positioned in another suitable calibration hole.<\/p>\n<p>This allows comparison calibration without relying exclusively on the internal temperature indication of the dry block calibrator.<\/p>\n<p>For accurate results, the influence of axial temperature distribution, radial temperature differences, sensor immersion depth and loading effects must be considered.<\/p>\n<h2>Compatible Reference Thermometer Readouts<\/h2>\n<p>The Additel AccuMac AM 1730 can be used with suitable high-accuracy resistance thermometer readouts.<\/p>\n<p>Examples include compatible Additel temperature measurement instruments.<\/p>\n<p>The readout must support the resistance range and measurement characteristics of the reference thermometer.<\/p>\n<p>Depending on the selected connector configuration, adapters may be required.<\/p>\n<p>Available connection options include:<\/p>\n<ul>\n<li>Additel smart connector<\/li>\n<li>Four-wire spade connector<\/li>\n<li>Compatible connector adapters<\/li>\n<\/ul>\n<p>The correct connection type should be selected when ordering the thermometer.<\/p>\n<h2>ISO\/IEC 17025 Accredited Calibration Included<\/h2>\n<p>The Additel AccuMac AM 1730 is supplied with an ISO\/IEC 17025 accredited calibration.<\/p>\n<p>This provides documented metrological traceability.<\/p>\n<p>The calibration certificate contains the relevant calibration results and associated measurement uncertainties.<\/p>\n<p>For precision temperature measurement, the individual calibration coefficients should be used whenever supported by the thermometer readout.<\/p>\n<p>Regular recalibration is recommended according to the instrument&#8217;s use, stability history and required measurement uncertainty.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>Additel AccuMac AM
