The OBS-GO Series Plastic Pressure Gauge is the most accurate pressure gauge available on the market. Built with a thermoplastic polypropylene enclosure, these gauges are engineered to endure in the most corrosive environments.

Each OBS-GO Chemical Pressure Gauge features a ¼” NPT 316SS connection, making it a perfect match for our GI Series Pressure Gauge Guards when working with highly corrosive chemicals. These gauge guards protect the plastic pressure gauge from any corrosive media in the process system through an isolator.

Factory pre-filled for enhanced accuracy (0.75%), each OBS-GO Plastic Pressure Gauge is equipped with color range tabs—red, yellow, and green—that act as visual alerts for pressure changes, such as during bag or filter change-outs.
