Technel represents DH-Budenberg who manufacture a line of pneumatic and hydraulic test pumps which serve as pressure generators for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. These compact units can be used in the laboratory or workshop, or on site at the measuring point. The model CPP120-X comparison test pump is a pneumatic comparison test pump for the provision of pressure up to 120 bar (1,740 psi). The model CPP1200-X comparison test pump is a hydraulic comparison test pump for generating pressure up to 1,200 bar (17,400 psi). Both units are particularly notable for their compact dimensions, which are not altered during operation, since the adjustment spindle runs within the pump body.
