AnmodelA1164-in-1 multi gas detectoris an intrinsically safe device that can continuously detect the concentration of leakagegas. It is suitable for gas leak rescue in explosion-proof places, underground pipelines or mines, etc., and can effectively ensure the safety of workers, production equipment will not be damaged. The product uses natural diffusion to detect gases, and can detect methane, carbon monoxide, oxygen, and hydrogen sulfide gases at the same time. The sensitive element uses a high-quality gas sensor, which has excellent sensitivity and excellent repeatability; it adopts embedded microcomputer control, is simple to operate, and has complete functions,high reliability, with a variety of adaptive capabilities. Besides,italsoadopts LCD screen display mode to display real-time concentration, alarm status, communication status, battery and other information. It is intuitive and clear. The compact and beautiful portable design not only makes you love it, but also makes it easier for you to move around.In addition,the product shell is made of high-strength engineering plastics and composite anti-slip rubber.So ithas high strength, good feel, and is waterproof, dustproof, explosion-proof, anti-vibration, anti-static, and anti-electromagnetic radiation interference,etc.
