A vacuum meter should be compact and ready to use. A handheld vacuum gauge can be used to quickly and accurately test all different types of categories of your vacuum system. The compact vacuum meter works on benchtop units in the laboratory that can monitor and control the vacuum to complete systems of indicators, controllers, sensors, and calibrators. Complete vacuum systems measure Torr and mTorr using Pirani, stainless steel diaphragm, and silicon diaphragm type sensors. Also we have vacuum switches and transmitters, along with analog thermocouple vacuum gauges and controllers with process connections of 1/8" NPT(M), NW 16, and 1/2" OD smooth flange.
