The OBS Series is the industry's only integral molded one-piece plastic pressure gauge and gauge guard, offering a unique and industry-leading solution for pressure measurement in corrosive environments. Gauge guards protect the pressure gauge from corrosive media through an isolator.

OBS Pressure Gauges feature a one-piece design and come factory pre-filled, achieving an industry-leading accuracy of 1.5%. This eliminates the need for manual filling, saving users time and effort. The color range tabs—red, yellow, and green—serve as visual pressure alerts for filter or bag changes.

The OBS Series plastic pressure gauges are available in PVC, PP, and PVDF, all equipped with a Teflon® diaphragm, ensuring complete corrosion resistance. By engineering the entire unit, including the housing, in plastic, the OBS Series guarantees reliability even in the most corrosive environments.
