ELECTRONICS: The PHP 35/40 bar hand pump from E-Instruments is a Pneumatic Pressure/Vacuum generating unit which is especially designed for testing and calibrating Pressure Instruments. This pump is manufactured with high quality for reliable application in the lab and the field applications. There is a Pressure/Vacuum changeover switch in the pump, which is used to select either Vacuum or Pressure output.
The pump is equipped with a Vernier and Release Valve. The output Pressure/Vacuum of the Hand pump can be precisely adjusted while performing calibration. Release valve is used to release the built Pressure/Vacuum after calibration.
