Introduction
Introduction
/
The Methane Carbon Dioxide Meter is an intelligent, multi-functional, ultra-small digital methane gas concentration and carbon dioxide concentration detection and alarm instrument. It is mainly suitable for use in places where there is a risk of gas explosion in coal mines, such as the return air of the goaf area of the mining working face in coal mines. The methane concentration and carbon dioxide concentration are continuously detected in the electromechanical chamber of the tunnel belt transportation tunnel and other places. When the methane concentration and carbon dioxide concentration exceed the limit, the detector immediately emits audible and visual alarms, which can be carried by downhole cadres, ventilation managers, gas detectors, blasters, mining face workers, etc. for portable use.
/
The methane carbon dioxide detector uses imported infrared carbon dioxide sensors and high-performance catalytic combustion methane original components, microcomputer digital technology and new electronic devices. It has stable performance, accurate threshold response, rapid response and high precision. The usage method adopts humanized design and soft adjustment technology, which is simple to operate and convenient to use. The detector shell adopts a high-strength all-plastic structure, equipped with a push-button electronic membrane switch with high sealing performance, and a four-digit high-brightness red digital tube display. It has a novel structure, unique shape, small size, light weight, and easy to carry.
The instrument is named according to the following method
