OBS Series One-Piece Pressure Gauges

The OBS Series is the industry's only integral molded one-piece plastic pressure gauge and gauge guard. Gauge guards protect the pressure gauge from any corrosive media in the processing system via an isolator. The OBS Series Pressure Gauges are genuinely unique and industry-leading when pressure measurement in corrosive environments. OBS Pressure Gauges are a one-piece design and come factory pre-filled, resulting in an industry-leading accuracy of 1.5%. Eliminating the need for filling saves the user time and the difficulty of filling a gauge isolator. The three movable red, yellow and green range tabs are designed to act as a visual pressure alert for bag or filter change-outs. The OBS Series is available in PVC, PP & PVDF, all equipped with a Teflon™ Diaphragm, making the entire unit completely corrosion resistant and the perfect pressure gauge for chemical applications. Engineering the whole body in a plastic housing rather than just the gauge guard lets users know that the complete unit will stand up in even the most corrosive environments.
