Ace AI-PCAL1 Pressure Calibrator is used to generate the required pressure for calibrating the pressure instruments with a comparison method. In this method generally, pressure instruments are calibrated against a master instrument. The scope of reference calibration is to minimize the time required for calibrating a pressure instrument. Ace AI-PCAL1 Pressure Calibrator generates pressure through the hand-operated swirling handle. Reservoir for water/oil. All wetted parts are in Stainless Steel. Extensively used for calibration of Pressure Gauges, Pressure Transmitters, Pressure Transducers, Pressure Switches, etc.
