Explanations regarding metal dry block temperature calibrators

The test object (all types of temperature measuring devices, e.g., dial thermometers, resistance thermometers, temperature switches, thermostats, etc.) and the reference temperature measuring device (built into the calibrator or external reference) are subjected to the same test temperatures. The measured values of the reference are compared with the values of the test item. This allows conclusions to be drawn not only about the function of the test item, but also about its measuring accuracy and measured value deviation.

Please note that the information specified in the respective technical data regarding radial and axial temperature uniformity refers to specific immersion depths and may not apply to all immersion depths in every case. The temperature range specifications apply at an ambient temperature of +20°C.

The LR-Cal metal dry block temperature calibrators have an internal (built-in) reference. If its accuracy is insufficient, an external reference (with or without its own display) can be used.

The LTC-MP-3I option can be ordered for the LR-Cal metal dry block temperature calibrators. This provides 3 measurement inputs, 2 of which are for resistance thermometers or thermocouples and 1 of which is for analog signals (4-20 mA or 0-10 V). Here, you can connect, for example, a test object and an external reference sensor, or 2 test objects and a temperature transmitter. The values of these connected sensors are shown on the calibrator's display.

Furthermore, the LR-Cal Aq2Sp2 PC software is available as an accessory for the LR-Cal metal block temperature calibrators. This software can be used to control the calibrator via its USB interface, perform manual or automatic calibration of one or more test objects, load and endurance tests, thermostat tests, and create calibration certificates.
