The portable dry metal block temperature calibrator LR-Cal SOLAR is temperature source and reference instrument in one device, for checking and calibrating of all kind of temperature instruments, such as thermometer, RTDs, Thermocouples, Temperature switches, etc.
The ceramic equalizing block, whose large size suits the external dimensions, ensures a proper heat transmission as well as optimal stability and uniformity values. It's interchangeability makes it possible to test sensors of various lengths, with diameters ranging from 1 mm up to 26 mm.
The device is equipped with a counter-current forced air cooling system, which keeps the temperature in the upper part of the well low. This feature allows checking also of very short probes, without heating the connecting head or the handgrip.

Temperatur sensor calibration:
Automatic calibration routine for all type of temperature sensors with advanced features such reference sensor stabilization, time-calibration data are automatically populated and stored for printing report. This procedure can also be ran in manual mode to allow the operator to manually enter the data. This is particular useful when calibrating temperature device such as digital thermometer or analogue thermometers.
Simply set MAX and MIN value and the software will run an automatic stress test on single sensor or a batch.
Advance thermostat calibration:
Simply set the open and close temperature limits, type of thermostat, typ of test and the software will automatically run the test.
Indicated temperature ranges are valid at ambiemt temperature +20°C. The stated accuracy is based on ambient temperature +23°C and is guaranteed for 1 year.
To increase the measurement accuracy of the calibrator significantly, we recommend the -2I version of the temperature calibrator (with two measuring inputs) and the external high accurate reference probe LR-Cal LRT F.
