The sector performs the calibration by comparing pressure gauges in the measuring range from 1.3x105 Pa to 1x10-4 Pa. The types of calibratable meters are Pirani, Penning, Thermocouple, Bayard - Alpert, Convection, Bourdon, capacitive membrane, piezo and resistive meters.

1) p indicates the extended pressure in Pascal 2) If the instrument to be calibrated requires a particular set-up for carrying out the measurements, or the use of fittings compatible with the flanging standard, the cost of calibration will be higher. |
