Wireless hydrogen sulfide (H2S) sensor for mud logging unit

Wireless hydrogen sulfide (H2S) sensor for mud logging unit Wireless hydrogen sulfide sensor is used to measure H2S gas concentration in the environment .


H2S sensor can be used to measure H2S gas concentration in the environment continuously and send out 4 ~ 20mA standard signals which are proportional to the concentrations of the gases measured.



Supply voltage: 3.5-5VDC

Baseline deviation: < ±0.5 ppm

Zero offset (-40°C – +50°C): < ±0.4 ppm

Temperature range: -20°c — +40°c

Life expectancy: 2 years in the air

Repeated relinearity: < ±5%

Detection range: 0-100ppm T90

Reaction time: 20 seconds (at 20 degrees)

Protection level: IP67



The hydrogen sulfide sensor is a device for identifying hydrogen sulfide gas, which can effectively detect hydrogen sulfide gas that enters the confined space and is encountered during operation. The electrochemical hydrogen sulfide gas sensor works according to the electrochemical principle, and determines the concentration of the gas to be measured by measuring the magnitude of the Faraday current generated by the gas to be measured in the oxidation and reduction process of the electrolytic cell.



The sensor explosion-proof box is assembled with the mounting bracket , and the g-type holder is used to fix the sensor in a suitable position on the site. The sensor installation area should avoid electromagnetic interference as much as possible, and the cavity should be sealed when the sensor is working.



All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.



CNPS can ship the goods to you by Express, Air, or sea .
