Chauvin Arnoux C.A 1621 Thermocouple Probe Calibrator P01654621

Thermocouple probe calibrator

C.A 1621 Calibrator Comes Supplied With:

  • Soft case
  • 2 thermocouple adapters
  • 6 x AAA 1.5 V batteries
  • User’s manual in 5 languages


The advantage of this sort of instrument is that it can be used to calibrate an instrument without removing it from the process. It is also preferable to calibrate an instrument in its actual operating environment. Not all quantities can be handled in this way, however. For the moment, on-site calibrators are mainly used for electrical signals and temperature.

The C.A 1621, C.A 1623 and C.A 1631 calibrators are ideal for industrial companies involved in developing and verifying measurement chains: whether you are an installer or a maintenance technician, whether you belong to the maintenance department or technical and general services, and whether you work in metallurgy, the steel industry, agri-food, hospitals or civil engineering, these instruments will meet your needs!

The compact, simple-to-use C.A 1621 thermocouple temperature calibrator is capable of measuring and simulating up to 8 types of thermocouples (J, K, T, E, R, S, B, N), as well as a voltage in mV. When used as a battery-powered stand-alone instrument, it offers a long battery life in the field. When connected to the mains, it can be used continuously without any time limit.

These calibrators offer two major functions: simulation and measurement.

Simulation The first function involves simulating a signal or generating a quantity with precisely-defined values. These quantities are applied upstream of the measurement chain.

Measurement The second function, involving the measurement of the signal. If there is a panel meter at the end of the chain, you can compare its value with the one indicated by the calibrator. If there is no panel meter, the simulated input value is compared with the signal measured by the calibrator.

The whole range of calibrators (C.A 1621, C.A 1623 and C.A 1631) is designed to accurately measure, generate or simulate all the low-level signals encountered in industry. Because they are simple to use, they are ideal for on-site work. Due to the wide variety of sensors recognized, these instruments are suitable for all your applications. Powered by batteries, these calibrators are stand-alone instruments offering a long battery life. When connected to the mains, they can be used continuously for as long as necessary!
