Pressure test pumps are also known as:

LR-Cal  pressure test pumps serve as portable pressure generators for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements.

These pressure tests can be carried out statically in the laboratory or workship, or on site at the measuring point.

All LR-Cal pressure test pumps are 100% tested for functionality, performance and tightness.

The pressure test pump LR-Cal  LPP 700/1000 is used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshop or on site at the measuring point.

If the instrument to be tested and a sufficiently accurate reference measuring instrument are connected up to the test pump, the same pressure is applied to the two measuring instruments when the pressure test pump LR-Cal  LPP 700/1000 is operated. By comparing the two measure valuses at random pressure values, the accuracy can be verified or the instrument under test can be adjusted.

Despite its compact dimensions, the pressure test pump LR-Cal  LPP 700/1000 is easy to operate and allows for exact generation of the required test pressures The LR-Cal  LPP 700/1000 is fitted with a fine adjustment valve for a precise adjustment of pressures.

The reference instrument is screwd directly on the top of the pump and the unit under test is connected by means of the connection tube incorporating an adapter 1/4" BSP female thread (freely rotating), contained in the scope of delivery.

The pressure test pump LR-Cal LPP 08 is used to generate pressure and vacuum for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements in the low-pressure and vacuum range. The pressure tests may be carried out in laboratories, workshops or on site at the measuring point.

The LR-Cal LPP 08 is a pneumatic pressure test pump for low-pressure ranges up to 8 bar with change-over switch to vacuum down to -850 mbar. Despite its compact dimensions, the pressure test pump is easy to operate and allows for exact generation of the required test pressures. The maximum pressure or vacuum achievable depends on the attached test volume. The smooth-running pressure generation and the integrated fine adjustment valve allow a safe and precise setting of very small positive resp. negative pressure values in the range of mbar.
