Portable 4 in 1 Gas Sensor multi CO LEL O2 H2S Gas Analyzer
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, rechargeable battery, and simple use. It is widely used in the 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 on the relevant
equipments.
