ability to generate temperatures significantly below ambient temperature is particularly useful for calibrating sensors used in refrigeration and environmental monitoring.<\/p>\n<h2>High Temperature Accuracy<\/h2>\n<p>The AMETEK RTCt-157 provides excellent temperature accuracy.<\/p>\n<p>The manufacturer specifies different accuracy values depending on the reference configuration.<\/p>\n<h3>Accuracy with Internal Reference<\/h3>\n<p>When using the internal temperature reference, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.11 \u00b0C<\/strong><\/p>\n<p>This specification applies to the A, B and C configurations.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When using the specified STS-200 external reference sensor, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.040 \u00b0C<\/strong><\/p>\n<p>This value describes the accuracy relative to the reference standard over a 12-month period.<\/p>\n<h3>Total System Accuracy<\/h3>\n<p>With the specified external reference sensor and accredited system calibration, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.065 \u00b0C<\/strong><\/p>\n<p>This specification includes the reference sensor and calibration uncertainty under the defined conditions.<\/p>\n<p>The distinction between internal accuracy, external reference accuracy and total system accuracy is particularly important when evaluating the uncertainty of a calibration procedure.<\/p>\n<h2>Excellent Temperature Stability of \u00b10.005 \u00b0C<\/h2>\n<p>The AMETEK RTCt-157 provides outstanding temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.005 \u00b0C<\/strong><\/p>\n<p>Temperature stability describes the temperature variation over time under defined operating conditions.<\/p>\n<p>The manufacturer evaluates stability after the stability indicator has been active for 15 minutes, followed by a 30-minute measurement period.<\/p>\n<p>Excellent temperature stability is essential for accurate comparison calibrations.<\/p>\n<p>It helps minimize measurement variations when calibrating precision resistance thermometers and industrial temperature sensors.<\/p>\n<p>The temperature display resolution can be selected down to 0.001 \u00b0C.<\/p>\n<h2>Patented Dynamic Load Compensation<\/h2>\n<p>One of the most important features of the AMETEK RTCt-157 is its patented Dynamic Load Compensation technology.<\/p>\n<p>Dynamic Load Compensation, or DLC, is designed to compensate for temperature differences caused by sensor loading.<\/p>\n<p>When several temperature sensors are inserted into a calibration block, their thermal characteristics can influence the temperature distribution.<\/p>\n<p>Large sensors and sensors with different diameters may introduce additional thermal loads.<\/p>\n<p>The DLC system helps compensate for these effects and improves temperature uniformity within the calibration insert.<\/p>\n<p>This is particularly useful when calibrating several sensors simultaneously.<\/p>\n<p>The AMETEK RTCt-157 also provides graphical information about DLC performance.<\/p>\n<p>This allows users to monitor the compensation process during calibration.<\/p>\n<h2>Active Dual-Zone Temperature Control<\/h2>\n<p>The AMETEK RTCt-157 features active dual-zone temperature control.<\/p>\n<p>The system uses two independently controlled temperature zones.<\/p>\n<p>The lower zone provides precise temperature control within the calibration area.<\/p>\n<p>The upper zone compensates for heat losses caused by the open top of the calibration block and the inserted temperature sensors.<\/p>\n<p>This technology helps reduce axial temperature gradients.<\/p>\n<p>Combined with Dynamic Load Compensation, the dual-zone system provides excellent temperature uniformity.<\/p>\n<p>This is particularly important for calibration procedures involving multiple sensors or sensors with different dimensions.<\/p>\n<h2>Advanced Touchscreen Interface<\/h2>\n<p>The AMETEK RTCt-157 features a modern touchscreen interface.<\/p>\n<p>The display provides intuitive access to temperature settings, calibration functions and measurement information.<\/p>\n<p>Users can navigate directly between operating modes and configure calibration procedures.<\/p>\n<p>The touchscreen interface simplifies everyday operation and reduces the number of manual steps required during calibration.<\/p>\n<p>The display can present temperature values, stability information and graphical measurement data.<\/p>\n<p>This makes the instrument suitable for both experienced calibration technicians and industrial maintenance personnel.<\/p>\n<h2>Automatic Graphical Stability Monitoring<\/h2>\n<p>The AMETEK RTCt-157 includes an advanced graphical monitoring system.<\/p>\n<p>The instrument displays temperature changes in real time.<\/p>\n<p>During heating or cooling, the graph provides an overview of the temperature approaching the selected setpoint.<\/p>\n<p>Once the calibration block reaches the required stability, the display automatically switches to a more detailed graphical representation.<\/p>\n<p>This allows small temperature deviations to be identified more easily.<\/p>\n<p>The graphical display helps users evaluate temperature stability before recording calibration results.<\/p>\n<p>This feature is particularly useful for demanding calibration procedures requiring stable temperature conditions.<\/p>\n<h2>Wi-Fi, Ethernet and USB Communication<\/h2>\n<p>The AMETEK RTCt-157 provides flexible communication options.<\/p>\n<p>The instrument supports:<\/p>\n<ul>\n<li>Wi-Fi<\/li>\n<li>Ethernet<\/li>\n<li>USB<\/li>\n<\/ul>\n<p>Integrated Wi-Fi allows remote access through a compatible web browser.<\/p>\n<p>Users can monitor temperature values and control supported functions without standing directly in front of the calibrator.<\/p>\n<p>This is particularly useful when the instrument is installed in a laboratory, cleanroom or production environment.<\/p>\n<p>Ethernet and USB communication support integration into suitable calibration systems.<\/p>\n<p>Remote operation can help improve efficiency when performing automated or repetitive calibration procedures.<\/p>\n<h2>Two Sensor-Under-Test Inputs<\/h2>\n<p>The AMETEK RTCt-157B provides two sensor-under-test inputs.<\/p>\n<p>These allow two compatible sensors to be measured during the<\/p>\n<p data-start=\"14915\" data-end=\"15020\"><a class=\"download-datasheet\" href=\"#\"
