Rosemount™ 628 Universal Gas Sensor

Electrochemical toxic gas sensors offer high specificity, fast response, and long life.

The Rosemount 628 Series of electrochemical toxic gas sensors provides high specificity, fast response and long life. All Rosemount 628 Sensors are compatible with the Rosemount 928 Wireless Gas Monitor. The electrochemical sensor cell incorporates industry-standard technology that is used in conventional wired gas detectors to bring consistent toxic gas sensing to challenging and remote locations. Gas sensor types include hydrogen sulfide (H2S), carbon monoxide (CO), and oxygen depletion (O2).

Key Features
