Test pumps serve as pressure generators for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. These units can be used in the laboratory or workshop, or on site at the measuring point. Easy operation By connecting the test item and a sufficiently accurate reference pressure measuring instrument to the test pump, the same pressure will act on both measuring instruments. By comparison of the two measured values at any given pressure value, a check of the accuracy and/or adjustment of the pressure measuring instrument under test can be carried out. Easy handling The model CPP1200-X comparison test pump is a hydraulic comparison test pump for generating pressure up to 1,200 bar. It is technically identical to the instrument base of the model CPB3800 pressure balance. The integrated dual-area spindle pump with switching valves enables rapid filling of the test system and smooth pressure generation.
