1. MJK-200-AI16 gas detector adopting high-quality catalytic gas sensor and SMD arts and crafts, has advantages of good reproducibility, disturbing-proof against temperature and humidity, long life-span and easy operation, so it is suitable for gas detection for industrial use.
2. It can transfer the gas concentration in air into digital signal output. It adopts output of 4-20mA three-line electric current signal, which has advantages of long-distance transmit and good disturb-proof.
3. It is suitable for gas detection in refineries, chemical plant, LPG station, gas boiler, and Spray-Paints etc where gas leakage easily.
4. Application The detector working with gas controller are widely used to detect gas in refinery, chemical plant, LPG station, boiler room, painting plant and other places with gas exists, effectively protect personnel and plant from flammable, toxic and oxygen hazards.
