Electrochemical H2S Sensor ME3-H2S
Summary:
ME3-H2S electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
Feature:
* Low consumption
* High precision
* High sensitivity
* Wide linear range
* Good anti-interference ability
* Excellent repeatability and stability
APPLICATION
Urban underground pipe gallery is a municipal public facility that implements unified planning, design, construction and maintenance, and is built in the city underground for laying municipal public pipelines.During the construction of the urban underground comprehensive pipe gallery, the workers are actually working in a closed environment or a closed space.
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.
Livestock and poultry farming is the major emission of ammonia gas, and these ammonia gas react with the oxidation products of sulfur dioxide and nitrogen oxides to generate ammonium nitrate and ammonium sulfate, which are an important source of PM2.5.
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.
Common toxic and harmful gases can be divided into irritating gases and asphyxiating gases according to their toxic properties.
Coal Mining Industry Poison Gas Monitoring
Flammable gas is mainly detected by catalytic sensor, mainly measuring 100% LEL, and also using thermal conductivity components to measure 100% VOL. High-end gas detection products in the petrochemical industry are gradually using infrared gas sensors, which can measure 100% LEL and 100% VOL. At the same time, laser beam technology is also gradually being used in the petrochemical industry.
