OBS-A Panel Mount Pressure Gauge

Brand: Truflo®

The OBS-A Series is the industry’s only integral molded one-piece plastic pressure gauge and gauge guard. 

Gauge guards are utilized to protect the pressure gauge from any corrosive media in the process system via an isolator. 

The OBS-A Series Pressure Gauges are truly unique and industry leading when it comes to pressure measurement in corrosive environments. 

OBS-A 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 having to fill a gauge isolator. 

The 3 movable red, yellow and green range tabs are designed to act as a visual pressure alert for bag or filter change-outs. 

The OBS-A 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 entire body in a plastic housing rather than just the gauge guard allows users to be confident that the complete unit will stand up in even the most corrosive environments.
