It is mainly used to protect the safety of personnel and detect data exposed to extreme environments, the highest measurable carbon monoxide concentration data , it uses imported electrochemical sensors, which are sensitive, accurate and reliable. The instrument adopts a sturdy engineering plastic shell and good protection design, and can be used in explosive environments such as gas and dust. The instrument is small and lightweight and can be easily clipped to a belt, shirt pocket or helmet. The ultra-large high-brightness liquid crystal is still clearly visible in the dark underground, and can read data such as gas concentration, time, and electricity. If the current gas concentration value exceeds the preset limit value, the instrument will alert the user with audible and visual alarms.
This instrument has reliable performance, reasonable structure and is easy to use. It is suitable for situations where there is a risk of gas explosion and coal and gas outburst. Suitable for use in mine rescue coal mine working face return air tunnel, etc.
