Product Description

Toxic gas detection alarm

Brief description: 
Toxic gas detection alarm can be used in places where flammable and explosive gas leaks and in chemical plant areas where toxic and harmful gases exist. The gas detection instrument adopts foreign catalytic combustion sensors and American imported electrochemical sensor technology. The product has the advantages of stable signal and high precision. The instrument housing 
The gas detection transmitter with display can be used in places where flammable and explosive gas leaks and in chemical plant areas where toxic and harmful gases exist. The gas detection instrument adopts foreign catalytic combustion sensors and American imported electrochemical sensor technology. The product has the advantages of stable signal and high precision. The instrument casing adopts cast aluminum one-time molding explosion-proof and flameproof design, and the wiring method is suitable for various hazardous places.
Toxic gas detection alarm instruments are widely used in pharmaceutical, chemical fertilizer, natural gas pipeline network, sewage treatment, municipal, iron and steel smelting, acetylene plant, refrigeration workshop, chemical workshop, gas station area, boiler room, hotel kitchen operation room and other places that require anti-toxic, fire and explosion.

Features:

1. Alarm record query function
2. Detection accuracy and range are adjustable
3. Long life, high sensitivity, low drift, stable and reliable operation
4. Sensor fault self-check, two-level concentration alarm, with relay output function
5. Liquid crystal or digital tube digital display of gas concentration and working status
6. With temperature compensation and automatic zero point correction function
7. 4-20mA or RS485 digital output, can be uploaded to DCS, PLC system
8. Infrared remote control mode, the detector can be adjusted without opening the cover, safe and convenient
9. The flameproof design is suitable for hazardous areas 1 and 2
