Application areas

Hand test pumps serve as 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 in the laboratory or workshop, or on site at the measuring point.

Easy operation

If one connects the test item and a sufficiently accurate reference measuring instrument to the hand test pump, on actuating the pump, 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 test item can be carried out. In order to approach the measuring points exactly, the hand test pump features a fine adjustment valve.

Easy handling

The hand test pump model CPP100-M allows, without external pressure supply, to generate a pneumatic test pressure up to 100 bar (1,500 psi) very easy and precise. The comparison test pump can also use for vacuum generation up to -950 mbar (-14 psi).

The maximum pressure or vacuum achievable is dependent upon the connected test volume.

For the precise setting for accurate comparative testing, the pump features a fine adjustment valve. The reference instrument and the device under test can screwed into one of the pressure ports. Both pressure ports feature a free rotating knurled nut with a M 20 x 1.5 female thread. The free rotating knurled nut enables the orientation of the instruments.

The scope of delivery contains two adapters to G ½” female thread and ½” NPT female thread each.
