Description
The Rosemount 628 series of electrochemical toxic gas sensors provide high specificity, fast response, and long life. All Rosemount 628 series sensors are compatible with the Rosemount 928 Wireless Gas Monitor. The electrochemical sensor cell incorporates the industry-standard technology that is used in conventional wired 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).
