CJR4/4 Infrared Methane and Carbon Dioxide AnalyzerDetailed product description：

The CJR4/4 methane and carbon dioxide analyzer (infrared) (hereinafter referred to as the detector) is an intelligent, multifunctional, ultra small digital methane (gas) concentration and carbon dioxide concentration detection and alarm instrument. It is mainly suitable for places with gas explosion hazards in coal mines, such as coal mine tunnels, mining workfaces, goafs, return air tunnels, belt transportation tunnels, mechanical and electrical chambers, etc., to continuously detect methane concentration and carbon dioxide concentration. Automatically record and store one frame of data every half hour; When the methane concentration and carbon dioxide concentration exceed the limit, the detector immediately emits sound and light alarms. When the methane alarm is triggered, a frame of data is automatically recorded and stored every 10 seconds, and when the carbon dioxide alarm is triggered, a frame of data is automatically recorded and stored every 1 minute. The detector can be used permanently in the above-mentioned places, or carried and used by underground personnel, ventilation management personnel, gas detectors, blasting personnel, mining face workers, etc.

The CJR4/4 infrared methane and carbon dioxide analyzer adopts high-performance sensors, microcomputer digital technology, and new electronic devices, with stable performance, accurate threshold, rapid response, and high accuracy. The usage adopts humanized design and soft adjustment technology, with simple operation and convenient use. The shell of the detector adopts ABS high-strength all plastic structure, equipped with high sealing performance button type electronic film switch, four high brightness red digital tube display, novel structure, unique shape, small size, light weight, and easy to carry.

In addition to the automatic data recording and storage function (which can be read out at any time) mentioned above, the detector also has various practical functions such as clock display, battery working voltage detection, alarm point (threshold) display, as well as multiple self-protection functions such as under voltage alarm, under voltage automatic shutdown, super concentration alarm, super concentration automatic shutdown, etc., thus reaching the leading level of similar products in China.
