VG-760 is a digital vacuum gauge for obtaining accurate vacuum measurements during filling refrigerants. It features a professional vacuum sensor to precisely test vacuum. The evacuation of an HVAC and refrigeration system is to evacuate the air and moisture in the system, which, if mixed with refrigerants, may produce an acidic chemical reaction, causing damages to the system in long term. Generally, a system vacuum should be below 700 micron so that the moisture in the system can be effectively reduced. The best vacuum is 300 micron. Common refrigerants cannot meet this requirement. VG-760 is used to test system leak and discern vacuum pump quality.
