These innovative calibrators have been designed for on-site applications as well as for the severe conditions of the naval and marine sectors.
Their ease of use and their compact and practical design make them unbeatable in industrial processes where the calibration of the temperature measurement systems is essential for the control of the process and the quality of the final product.
Special attention is paid to reduce weight, size and to reinforce robustness by using an aluminium body as well as aluminium and stainless steel for many internal parts.

Each calibrator is tested in our laboratory and calibrated with our references in accordance with the international standard. At this stage all the functions are checked against reference parameters and a calibration protocol is issued.


The thermal part of these calibrators is made of a metal block heated with resistors or with Peltier thermoelectric modules. In the metal block there is one bore in which the interchangeable insert is placed.

With the available standard inserts, the calibrators are versatile and can be easily adapted for the calibration of temperature probes with the most common diameters.

Customer-specific inserts and bores are available on request.
