Quadrigauges are a combination of three gauges in one case performing four gauge functions. Continuous system pressure readings are indicated on one of three simultaneous reading gauges through a pressure range of 0 – 3000 psi, 0- 5000 psi or 0 – 6000 psi, depending on the Quadrigauge selected. The low and medium pressure gauges are protected at higher pressures by means of pressure sensitive valves which restrict gauge pressure. The 3000, 5000 and 6000 psi gauges indicate continuous pressure through the total range.
Quadrigauges have unlimited versatility for testing working pressure in brake, hydraulic and air systems on a wide variety of vehicles and equipment in the agricultural, mining, construction, utilities and forestry industries. These instruments are also useful for testing pressures on equipment such as aerial ladders, scissor lifts, winches, cranes, dump trucks, fire equipment, tailgate lifts and forklift trucks to name just a few.
