The portable metal block temperature calibrator LR-Cal PYROS 375-DNV has been specially developed for simple and portable use on site. Special emphasis was placed on a low overall weight and easy handling. The housing is made of robust aluminum and many internal parts are made of stainless steel. Each LR-Cal PYROS 375-DNV temperature calibrator is calibrated in the laboratory at the factory.
The thermal parts of the calibrators, i.e. the calibration temperature source, consist of a solid metal block that is heated or cooled with Peltier elements. There are one or more holes in the metal block for inserting the test specimens. Special insert sleeves offer further options for processing test specimens with different diameters. Shorter reaction times during the heating and cooling phases and rapid stabilization save time during multi-point calibration processes.
An innovative ventilation system on the device makes it possible to keep the temperature on the top of the calibrator lower than on devices from other manufacturers. This system does not direct the hot exhaust air upwards towards the test specimens, but out of the housing to the rear.
Thermographic images taken at 650°C:
Third-party products: at +650°C the test specimen heats up to approx. 69.6°C
LR-Cal PYROS devices: at +650°C the test specimen heats up to approx. 27.5°C
As a result, the measuring head of the test specimen and the electrical connections are exposed to a significantly reduced temperature and possible temperature compensation errors are significantly reduced.
