1、 Introduction
It is mainly used to protect personnel's life safety, detect high concentration CO data exposed to extreme environments, and can measure carbon monoxide concentration data up to 10000ppm. For example, in rescue situations after an explosion, it uses imported electrochemical sensors, which are sensitive, accurate, and reliable. The instrument adopts a sturdy engineering plastic shell and a good protective design, which can be used in explosive environments such as those with gas and dust. The instrument is compact and lightweight, making it easy to clamp onto belts, shirt pockets, or helmets. The ultra large and high brightness OLCD LCD 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, the instrument will alert the user with sound and light alarms.
This instrument has reliable performance, reasonable structure, and easy use, and is suitable for situations with gas explosions and coal and gas outbursts. Suitable for use in mine rescue, coal mining working faces, return air tunnels, etc.
