The OBS-GO4 Series Plastic Pressure Gauge features an extra large color display and is the industry’s most accurate pressure gauge on the market. With a Thermoplastic Polypropylene enclosure, OBS-GO4 Series plastic pressure gauges were engineered to last in the most corrosive environments.
A ¼” NPT 316SS connection comes standard on all OBS-GO4 Plastic Pressure Gauges. This connection allows for them to be a perfect mate with our GI Series Chemical 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.
OBS-GO4 Plastic 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 OBS-GO4 Pressure Gauge is also 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.
