• Simple and ergonomic handling
• Compact dimensions
• Low weight

Application areas

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 statically 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 pressure measuring instrument under test can be carried out. In order to approach the set-point exactly, the hand test pump features a fine-control valve.

Easy handling

The CPP7 is a pneumatic hand test pump for low-pressure ranges up to 7 bar, with switching to vacuum generation down to -850 mbar. The maximum pressure or vacuum achievable is dependent on the connected test volume. Through the smooth pressure generation and the integrated fine-adjustment valve, very small positive or negative pressures in the mbar range can be set safely and precisely.

Via a T-connector with a hose connection, the test item and the reference measuring instrument can be easily connected.
