Dwyer Instruments differential pressure gauges are visual indicators designed to measure and illustrate the difference between two pressure points within a process system. These gauges offer a full-scale accuracy of 2% while measuring positive, negative or differential pressure values. The unique design of these units is capable of resisting shock, vibration and over-pressures with no manometer fluid to evaporate and freeze, as well as cause toxic or levelling problems. They are also suitable for checking the gas-air ratio control and monitoring blood and respiratory pressures in medical care equipment. Choose from a range of these differential pressure gauges available in 4 inch and 4-1/2 inch dial sizes on Raptor Supplies.
