Description [HIGH PRECISION DETECTOR]Our carbon monoxide detector uses a professional high precision sensor, the CO detector can continuously monitor the concentration of CO gas in the surrounding environment, ensure that excess CO gas is detected in the air, once the gas concentration reaches the level of the warning, the CO gas leak detector will sound and vibration. remind the operator to take relevant measures.[HIGH EFFICIENCY, LOW POWER CONSUMPTION]The handheld CO detector reacts quickly, and the response time is Less than 60s. portable carbon monoxide detector has an automatic calibration function, the CO concentration range that the carbon monoxide meter can measure is 0~1000PPM, Very high accuracy ( 5% or 10PPM). The carbon monoxide meter handheld can auto power off in 10 minutes without any operation, saves battery consumption and has long standby time.[HIGH-QUALITY DETECTOR]Our carbon monoxide meter uses a high-quality and clear LCD large screen, with clear characters and easy to read. The housing of the CO detector is made of high-toughness ABS engineering plastics, good wear resistance, which is comfortable to the Press , strong, and durable. Gas detector sensor performance is stable and accurate, in the case of accidental drop, still can protect the sensor without damage, let you rest assured that safe use.[EASY TO CARRY AND WIDELY APPLICATION]Our handheld carbon monoxide meter humanized design, comfortable grip, small size, light weight, easy to carry and operate. Portable carbon monoxide detector is widely used in metallurgy, petroleum, chemical industry, power plants, coal, paper, municipal, tunnels, food, textile and other places, can effectively prevent the occurrence of CO exceeding the standard.Battery: No. 3 and No. 7 batteries(Without battery)Colour:yellowMaterial:ABS Package Contents:1 set * carbon monoxide detectorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
