Four-in-one gas detector, high precision, triple alarm (audible, visual and vibrating), large screen with high-definition backlight, capable of detecting CO, H2S, O2, LEL and other gases

General Description

The Blue 4-in-1 Gas Detector is a portable and accurate detection device for identifying carbon monoxide (CO), hydrogen sulfide (H₂S), oxygen (O₂), and combustible gases (LEL). It features a high-definition LCD screen with backlight and a triple alarm (audible, vibrating, and visual) to ensure continuous and reliable monitoring of gas concentrations in a wide range of specialized environments such as ships, mines, and oil extraction. Its compact and lightweight design, with rechargeable batteries, makes it easy to carry and use.
