  • ME4-H2S-E4-1.png

Summary:

ME4-H2S-E4 hydrogen sulfide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with hydrogen sulfide and oxygen take place respectively on the working electrode and on the reference electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of hydrogen sulfide. So the concentration of the target gas could be got by measuring the value of current. The 4th electrode (auxiliary electrode) is used to compensate the zero current, to make it has the characteristics of strong signal level and low zero current.

Feature:

* High precision

* High sensitivity

* Short response time

* Good anti-interference ability

* High resolution, wide linear range

APPLICATION

Pollution Source Detection

The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.

Industrial Exhaust Monitoring

Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of the enterprise. These gases enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health.

Outdoor Air Quality Monitoring

Outdoor air quality monitoring is a process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. Air pollution monitoring is to measure the types and concentrations of pollutants in the atmosphere, and observe their spatial distribution and changing rules.
