Managing gas concentrations in tunnels and underground construction to ensure safety during work.
This is a system that monitors the concentrations of oxygen (O2), combustible gases (methane: CH4), hydrogen sulfide (H2S), and carbon monoxide (CO), and alerts construction personnel in case of any abnormalities. When the concentrations of these gases exceed or fall below the set threshold values, it triggers an alarm to enable prompt action.

basic information
***Features*** It can simultaneously measure four types of gases (oxygen, methane, hydrogen sulfide, and carbon monoxide) with a single sensor. Simple operations allow for changes to alarm values and data recording times. You can easily change the required alarm criteria and data storage settings at any time. Multiple detectors can be connected with a single control signal line. Up to 31 detectors can be connected (optional). By connecting an alarm device, it can trigger an alarm operation when the set reference value is "exceeded" or "not reached" (optional). Even on days when the site is closed, automatic notifications to mobile phones are possible if there is an abnormal gas concentration (optional).
