Description
Pressure Comparison Test Pumps
The LR-Cal pressure comparison test pumps serve as pressure generator for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. The devices can be used in the laboratory or workshops, or on site at the measuring point.
By connecting the test item (unit under test) and a sufficiently accurate reference pressure measuring instrument to the LR-Cal pressure comparator, 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.
All LR-Cal pressure comparators, manufactured in our own facilities in Kirchentellinsfurt in the south of Germany are 100% tested for performance, functionality and tightness, before they are shipped to our customers.
