Plast-O-Matic differential pressure gauges are designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressure points, while completely isolating the gauge function from the pressure chamber. No mechanical seals are required. Each of these devices are engineered for durability and performance. Maximum line pressure rating is 200 PSI.
