The LR-Cal pressure test pumps are used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurement. These pressure tests can be performed on a mobile basis, on site at the measuring point, or stationary in the laboratory or workshop.
If the measuring instrument to be tested and a sufficiently accurate reference measuring instrument are connected to a LR-Cal pressure test pump, the same pressure acts on both measuring instruments when the pump is actuated. By comparing the two measured values at any pressure values, a check of the accuracy or an adjustment of the pressure gauge to be tested can be made.
Despite their very compact dimensions, the LR-Cal manual test pumps enable simple and accurate test pressure generation. For precise adjustment for accurate comparison testing, the LR-Cal calibration hand test pumps have a fine adjustment valve.
We manufacture all LR-Cal pressure test pumps exclusively at our site in Baden-Württemberg (South of Germany), as well as components and individual parts.
All LR-Cal pressure hand test pumps are 100% performance and leak tested before leaving our factory.
