The Pressure comparison test pump ISP 100-P is used for generating pressure and vacuum for the testing, adjusting and calibration of mechanical and electronict pressure measuring instruments by means of comparison measurements. These pressure and vacuum tests can be carried out in laboratories, workshops or on site at the set measuring point.
When the device under test and a reference measuring instrument with an adequate accuracy are connected to the same pressure comparator, the same pressure will act on both measuring instruments after actuating the pump. A calibration or adjustment can be carried out by comparing the two measure values at any pressure or vacuum value.
