Description
Overview
GAOTek NH3 ammonia gas leak detector is applicable to II-level explosion-proof environment. Real-time detection of toxic, harmful, flammable and other gases. The concentration is converted into an electrical signal and transmitted to the monitoring equipment. If the concentration exceeds the set safety value, an alarm will be issued to remind the user to deal with or evacuate quickly. Main Features The detector working with gas controller can be used to detect gas in refinery, LPG station, chemical plant, boiler room, painting plant and other places where NH3 gas exists.
