Popularization of hydrogen sulfide sensor knowledge

User:JXCTUpload time:Dec 17 2021

Hydrogen sulfide is colorless, smells like rotten eggs at low concentrations, and dulls the sense of smell at high concentrations. Soluble in water, ethanol, glycerin, carbon disulfide. Mainly used in the manufacture of inorganic sulfides, and also used for chemical analysis, such as identification of metal ions. It is extremely flammable. It can form an explosive mixture when mixed with air. It can cause combustion and explosion when exposed to open flames and high heat. The gas is heavier than air and can spread to a considerable distance at a lower place, and will ignite when it encounters a fire source. It can explode if it reacts violently with concentrated nitric acid, fuming nitric acid or other strong oxidants. After hydrogen sulfide poisoning, headache, dizziness, irritability, staggering gait, irritability, confusion, delirium, epileptic convulsions may be generalized tonic-clonic seizures, etc.; coma may occur suddenly; dyspnea or breathing stop may occur heart stop. , So a H2S sensor that can test hydrogen sulfide is important.

The 485-type large-screen hydrogen sulfide sensor supports LCD button settings and has a screen lock function to imitate misoperation. All parameters can be set using button polarity. This product can be used in mining areas, home environments, gas pipelines, industrial environments and other scenarios.

Hydrogen sulfide gas monitoring (H2S sensor) has high sensitivity to H2S. The H2S sensor can detect 5ppm H2S gas, which is very suitable for H2S gas leak detection.


No fear of harsh environment: IP65 high-density material shell, built-in waterproof strip, moisture and dustproof, high temperature and high humidity environment, dust, rain and snow and other harsh environments can be used, -40 degrees Celsius to 80 degrees Celsius (customizable);

Support RS485/4-20mA/0-5V/0-10V/NB-IoT/LoRa/WIFI/Ethernet and other signal output to meet the needs of different environments. Wireless transmission, no wiring, low power consumption, stable performance;

It can be matched with cloud platform: with Jingxun cloud, the configuration interface can be configured according to the on-site situation, and data and alarms can be checked at any time;


H2S gas monitoring sensors can be widely used in harsh environments such as industrial plants/traffic tunnels, energy, electricity, petroleum and petrochemicals, coal mine roadways, gas drainage, and other industrial and agricultural environments (pollution emission monitoring, fruit tree gardens, agricultural pastures, agricultural greenhouses, flower breeding , Laboratories, etc.) health and safety monitoring.
