The MEXTECH GD-09 Portable Multi-Gas Detector can detect Explosive Gas (EX),
Oxygen (O2), Carbon Monoxide (CO) and Hydrogen Sulphide (H2S) continuously and simultaneously. It is used
to monitor for the presence of combustible, flammable, and toxic gases, as well as oxygen depletion. 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 equipment.
| Target Gas | Range | Low alarm | High alarm | Resolution |
| EX | 0~100%LEL | 20%LEL | 50%LEL | 1%LEL |
| H2S | 0~100ppm | 10ppm | 35ppm | 1ppm |
| CO | 0~1000ppm | 50ppm | 150ppm | 1ppm |
| O2 | 0~30%vol | 19.5%vol | 23.5%vol | 0.1%vol |
