Detector Description
Our portable multi-gas detector with a large LCD. It can monitor CO, H2S, O2, and combustible gas simultaneously. The instrument with audio/visual and vibratory indicators, a rechargeable battery, and simple use.
It is widely used in an area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers’ life and avoid damage to the relevant equipment.
