Our company's flow sensors are calibrated by default under conditions of 20°C, 101.325 kPa, and using air as the reference. The production environment is maintained at a temperature of 22±2°C, in a cleanroom setting with 30%–35% relative humidity. If special requirements exist, calibration will be performed according to the customer's specifications.
