What is temperature calibration with a metal block temperature calibrator?
The test item (temperature measuring instruments of all types, e.g. dial thermometers, glass thermometers, resistance thermometers, temperature switches, thermostats, etc.) and the reference temperature measuring instrument (installed in the calibrator or external reference) are both subjected to test temperatures. The measured values of the reference are compared with the values of the test item. In this way, a statement can be made not only about the function of the test item, but also about the measurement accuracy or the measured value deviation of the test item.
Please note that the specifications regarding radial and axial temperature uniformity given in the respective technical data refer to specific immersion depths and do not necessarily apply to all immersion depths in every case. The temperature range specifications apply at an ambient temperature of +20°C.
The LR-Cal metal block temperature calibrators have an internal (built-in) reference. If its accuracy is not sufficient, an external reference (without or with its own display) can be used.
The LTC-MP-3I option is available for LR-Cal LTC metal block temperature calibrators (except for versions LTC-DB-0550-60 and LR-Cal LTC-DB-1200-35), with three measurement inputs (2 x for RTD/TC and 1 x for analog signal 4... 20 mA/0...10 V).
The LR-Cal LTC-DB-0550-60 metal block temperature calibrator is available in two versions: standard version and “-2I” version with 2 measuring inputs (for RTD/TC).
This option is not available for the LR-Cal metal block temperature calibrators of the compact PYROS series.
Furthermore, the LR-Cal Aq2Sp2 PC software is available as an option for the LR-Cal metal block temperature calibrators. This allows the calibrator to be completely controlled from the PC via its serial interface, manual or automatic calibration of one or more DUTs, load and life tests, thermostat tests, as well as the generation of calibration certificates.
