Easy to use and equipped with a large graphic screen, the TC temperature calibrators have been designed to simplify maintenance and commissioning of temperature sensors and transmitters. The TC 6621 calibrating thermometer measures or generates temperatures via 16 different thermocouples and voltages with an accuracy of 0.02%.

The TC 6622 calibrating thermometer measures or generates temperatures via 12 different resistive probes and resistors with an accuracy of 0.02%. With a low temperature coefficient (10 ppm / ° C in thermocouples and 7ppm / ° C in resistance), an IP54 case and a robust design, the CTs are particularly suitable for use in the field even in demanding environmental conditions. They are widely used in the energy, engineering, metallurgy and automotive sectors.

TC calibrators have a graphical interface simplifying programming and reading. Internal data management makes it possible to display the measurements in the form of text or a graph. Adapted to the different working modes of the process world thanks to the scaling and to the different specific calibers, they can also be associated with the DATACAL calibration software for the exploitation and the traceability of the data, as well as the edition. customizable calibration reports. As standard the CTs are supplied with 4 AA type batteries. The battery charger option uses a rechargeable battery pack directly from the mains.
