Type hydrogen sulfide sensor
1. Overview
The hydrogen sulfide sensor is an intrinsically safe sensor that adopts electrochemical principles, intelligent control by an embedded microcontroller, and a three-digit digital tube display. It is mainly suitable for continuous measurement of hydrogen sulfide concentration in explosive gas environments such as coal mine underground mining working faces, return air tunnels, and electromechanical chambers. The instrument can measure and display the instantaneous concentration of hydrogen sulfide, alarm when it exceeds the limit, and output a frequency signal proportional to the measured hydrogen sulfide content. The instrument has the characteristics of wide measuring range, stable performance and high reliability. It can be used with various coal mine safety monitoring systems and power outage instruments.
