Hydrogen Sulfide Gas Sensor Module

March 20, 2002 -- The Model 4101-05 Hydrogen Sulfide Gas Sensor Module provides an industry standard linear 4-20 mA signal of Hydrogen Sulfide gas concentration with a range of 0-100 PPM H2S. This signal can interface with Sierra Monitor controllers or the user's own controller or DCS system. The Model 4101-05 provides accurate measurement in the low PPM range, features the field proven, reliable electrochemical sensor design, and self-diagnostics. In addition, its user-friendly design provides a low sensitivity check LED to inform the user when sensor replacement is due, false alarm avoidance features, and simple calibration.

This new gas sensor has a wide range of applications in the chemical, petrochemical and water/wastewater treatment industries continuously monitoring for toxic concentrations of this hazardous gas.
