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.
