Overview:
    The box-type manual pressure vacuum source integrates positive and negative pressure generation, manual pressure generation, light and convenient, superior sealing performance, can provide a stable air pressure source, simple operation, easy maintenance, and is an alternative to manual pumps. It is one of the main equipment for verifying pressure (differential pressure) transmitters, pressure sensors, ordinary (precision) pressure gauges and other pressure instruments. In the digital pressure calibration system, it is combined with our company’s precision digital pressure gauge or pressure calibration system. It can provide stable air pressure when used in conjunction with the tester.

main feature:
◆Manual pre-compression, remote transmission of calibration instrument
◆Good sealing and stable pressure
◆Precision fine adjustment, high fineness of adjustment
◆Closed structure, easy to carry, safe and reliable
◆Quick connector, convenient connection, reducing labor intensity
◆Integrated positive and negative pressure, easy to switch between positive and negative pressure
