Everything's fine.
Łukasz P. 05.09.2021 Confirmed purchase Translated review
Generally a good sensor, although working with the PT100 probe showed a constant temperature deviation. It is possible that the problem was with the pt100 probe - I do not know.

Story. They fired from the first start and are now measuring the temperatures of the electrician's batteries. Excellent quality and product and measurements.
