OBS-B Center Mount Pressure Gauge

Brand: Truflo®

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

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

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

OBS Plastic 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 pressure 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 Series Plastic Pressure Gauge 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.
