Accurate digital vacuum gauge with internal memory and waterproof housing for reliable vacuum tracking.
VGW-760 is a professional digital vacuum gauge for accurate vacuum measurement during refrigeration and HVAC evacuation.
Highly practical on-site thanks to multiple accessories, it ensures precise vacuum measurement and guarantees full degassing of moist vapors and non-condensable gases.
Its rugged design includes a reinforced housing and oil filter to protect the integrated Pirani sensor from HVAC system contaminants.
Bluetooth connectivity enables pairing with the AI-TOOLS app to access new features such as vacuum graphing, logging, and reporting.
Clear, precise readings
Ideal for professional vacuum pump control
Intuitive, standalone operation
Bluetooth connection via AI-TOOLS app
The pressure sensor integrated into the VGW-760 is designed to accurately measure micro-pressures. Its measurement range is between 0 mbar and 30 mbar. That is why the device will only start displaying values once the vacuum has dropped below 30 mbar. At atmospheric pressure and until the vacuum falls below 30 mbar, the VGW-760 screen will show dashes.
When the vacuum is very low and the vacuum pump is stopped, there is always a pressure rise corresponding to the decay phenomenon. In this case, the pressure rises and stabilizes between the vacuum and atmospheric pressure. This phenomenon is explained by the evaporation of residual moisture present in the system oil. This is normal and does not indicate a leak in the system. However, if the pressure quickly rises to atmospheric pressure once the vacuum pump is stopped, it indicates a leak. It is very unlikely that the leak comes from the vacuum gauge itself, as its sensor is hermetically sealed. More often, leaks come from the hoses and fittings connected to the system or from the valve (or solenoid valve) of the vacuum pump.
The device does not require specific maintenance unless it displays incorrect or inconsistent values. This may be caused by clogging of the sensor with system oil. A procedure for cleaning the sensor and replacing filters is described in the user manual.
