| Handhold CH4 & O2 gas detector |
|
 |
No: DSCH4O2
Details: 2 in 1 gas detector, testing two gases of ch4 and o2.
Application places: portable CH4/O2 Warning detector can be applied to detect the concentration of CH4 gas and the 02 in the coal mine, tunnel and other continuous monitoring environment. When the gas concentration is exceeded, the detector can make sound, light, vibration alarm automatically. It can be portable used by relevant staff, managers, professionals, mobile workers. Also it can be used in the above-mentioned fixed places.
