The WIKA CPP30 pneumatic hand pump is used for generating pressure to test, adjust and calibrate mechanical and electronic pressure measuring instruments by means of comparative measurements. Testing can take place in a laboratory or workshop, or on site at the measuring point. When the device under test and a suitably accurate reference measuring instrument are connected to the test pump, after actuating the pump, the same pressure will act on both measuring instruments. Calibration or adjustment of the device under test can be carried out by comparing the two measured values at any pressure value.
