Rechargeable Diffusion 4 in 1 Gas Detector Portable Multi Gas Detector CO H2S Oxygen Ex Meter
>>Overview
The Portable Gas Detector is a handheld gas detection instrument newly developed by JUGE Environmental Technology. Equipped with original imported sensors and a new 32-bit low-power ARM processor, it features a 1.77-inch TFT LCD screen that delivers clear, intuitive, and aesthetically pleasing displays. With three-button control, it offers excellent human-machine interaction for simple and convenient operation. The device supports dual-language selection (Chinese/English) and combines icons with text menu displays for practicality, intuitiveness, and elegance. It provides timely, accurate, and reliable alerts through audible, visual, and vibration alarms.Designed with a unique duckbill-style back clip for secure and convenient carrying, it supports USB charging for easy recharging. The built-in LED lighting function provides illumination during emergencies. Featuring an explosion-proof structural design, it is suitable for various hazardous industrial environments. This product is widely used in metallurgy, petroleum/petrochemical industries, municipal facilities, chemical wastewater treatment, and other sectors requiring continuous monitoring of flammable, explosive, toxic, and harmful gases.
