The OBS-TT Series Plastic ‘Tell-Tale’ Pressure Gauge is the industry’s most accurate pressure gauge on the market featuring a red ‘Tell-Tale’ pointer. With a Thermoplastic Polypropylene enclosure, OBS-TT Series pressure gauges were engineered to last in the most corrosive environments.
A ¼” NPT 316SS connection comes standard on all OBS-TT Plastic Pressure Gauges. This connection allows for them to be a perfect mate with our GO Series Pressure Gauge Guards when dealing with extremely corrosive chemicals. Gauge guards are utilized to protect the pressure gauge from any corrosive media in the process system via an isolator.
The Chemical Pressure Gauges come factory pre-filled, which is one of the main reasons we were able to achieve that industry leading accuracy of 0.75%. Each Pressure Gauge is equipped with Color Range Tabs. These 3 movable red, yellow and green range tabs are designed to act as a visual pressure alert for bag or filter change-outs.
