Calibration of pressure sensors in the laboratory is carried out by means of a 10 kg calibration weight of accuracy class E2. Weighs of such a large mass are customized. Currently, we carry out calibration of our existing pressure sensors by three weights of accuracy class E2: of 2 kg and 10 kg with a total weight of 12 kg. A smaller weight is also used to calibrate the moisture-proof scales for measuring the density of VIBRA CJ-6200ER ice (made in Japan).
