Hanzel Instruments

Portable diffusion O2/CO/H2S/LEL multi-gas detector is used to detect the 4 kinds of gases at the same time, highly accurate and fast response, The gas detector is applied in many industrial areas, including the chemical industry, petroleum, gas station, metallurgy, coal mine, agriculture, biology pharmaceuticals, power, lab research, and another industry environment. We provide gas detector OEM/ODM services.
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.
