This equipment is used to detect the gas concentrations of CO,CO2,O2 and CH4 outside the capsules.It is embed multi-parameter detector,the gas suck in pass through the detector and then their concentration detected by the detector,after that the gas will exhaust outside.

1. This equipment have four push-button for the handheld multi-parameter detector,turn on the battery when do detecting and turn off it when no detecting for power saving.
2. The detector is in sealed space,so gas leak is rarely happen.
3. The gas volume is up to 250ML per suck,the gas flow is up to 10L per minute,these index is enough for detecting.
