Description
4 in 1 gas detector is a versatile and portable digital device designed to monitor toxic gases like carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2), and lower explosive limit (LEL) levels. With a high-resolution display, it provides accurate measurements for various gases:
- O2 measurement range: 0~30%, resolution: 0.1%
- CO measurement range: 0~999PPM, resolution: 1PPM
- H2S measurement range: 0~100PPM, resolution: 1PPM
- LEL measurement range: 0~100%, resolution: 1%
The device features an adjustable alarm system with flash, vibration, and buzzer alerts, ensuring safety in diverse environments such as mines, metallurgical plants, petrochemical facilities, power stations, and municipal areas. It operates efficiently in temperatures ranging from -10℃ to 50℃ and humidity levels from 15% to 90% RH (non-condensing). Powered by a built-in 3.7V lithium battery, this gas detector is reliable and easy to use, making it essential for maintaining air quality and safety.
