PRECISION REFRIGERANT GAUGES

Superior Shock Resistance
Our unique patented design isolates the movement from the socket, reducing the effects of shock.

Superior Vibration Resistance
Our enhanced vibration dampening design cushions the movement for flutter-free performance and extended gauge service life.

Superior Pulsation Resistance
After 10 million cycles, these gauges show three times less wear than conventional gauges. The result is a longer lasting more reliable gauge.
