LPP 40, Calibration Handpump

Product Description

The LR-Cal LPP 40 pressure test pump is used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurement. These pressure tests can be carried out 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 the LR-Cal LPP 40 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 its very compact dimensions, the LR-Cal LPP 40 pressure test pump enables simple and accurate test pressure generation with the option of switching to vacuum generation. For precise adjustment for accurate comparative testing, the LR-Cal LPP 40 has a fine adjustment valve. The reference gauge is screwed directly onto the top of the pump and the test specimen is connected via the connection hose with free-running 1/4″ BSP female thread included in the scope of delivery, if necessary using suitable thread adapters
