Product Description

MIC200-IR4 Four-wavelength Point-type
Infrared Flammable Gas Detector| 30--50M




The MIC200-IR4 Four-band Infrared Flame Detector is Sight Gas detection System is a proven open path gas detection solution which aids in high speed detection of flammable gases such as Methane, Ethane, Propane, Butane, Pentane, Ethylene, Propylene, Butadiene in Short range (5 to 40m) distances comes with approved certification for ATEX.

It's a reliable and high-performance flame detector. It uses advanced flame analysis and identification technology to quickly respond to infrared radiation in a fire and has the highest false alarm immunity .
The MIC-200-IR4 detector contains three narrow-band infrared sensors (4-6 microns) and optical filters, which have high sensitivity to carbon dioxide emission spectra (4.4 microns), which can effectively eliminate interference and achieve detection for a much longer distance.
The special fire signal processing method and multi-sensor detection technology greatly improve the sensitivity and response time of the detector. The detector is suitable for liquid and gas fires, open flames with smoke and places where deflagration occurs.
