Thank you for buy our brand new vacuum gauge, please read this manual and become familiar with the specifications and operation of the gauge prior to use.
VGW-760 is a wireless digital vacuum gauge for obtaining accurate vacuum measurements during filling refrigerants. It features professional vacuum sensor to precisely test vacuum. The evacuation of a hvac and refrigeration system is to evacuate the air and misture in the system, which, if mixed with refrigerants, may produce acidic chemical reaction, causing damages to the system in long term. Generally system vacuum should be below 700 micron so that the moisture in the system can be effectively reduced. The best vacuum is 300 micron. Ordinary refrigerants cannot meet this requirement. VGW-760 is used to test system leak and discern vacuum pump quality.
