LRD—1型瓦斯检定器是根据各种气体有各自不同的热导系数的原理制成的,安全火花型携带式检测仪表。该仪器可同时兼测高、低浓度甲烷的含量。主要用于煤矿井下巷道、工作面等地大气中甲烷含量的日常检测,以及超级瓦斯矿井和抽放矿井高浓度甲烷的测量。该检定器由抚顺煤炭研究所研制、常州红旗仪表厂生产。该仪器自1979年开始生产至今已在全国30多个局矿使用,根据现场使用情况及要求,我们在仪器传感器、线路及结构等方
LRD-1-type gas detector is based on a variety of gases have different thermal conductivity of the principle of the principle, the safety of spark-based portable instrumentation. The instrument can detect both high and low concentrations of methane content. Mainly used for coal mine underground roadway, face and other places daily atmospheric methane content testing, as well as super-gas mines and pumping high concentration methane measurement. The verification device developed by Fushun Coal Institute, Changzhou Hongqi Instrument Factory production. The instrument has been produced in 1979 so far in the country has more than 30 bureau mine use, according to the site use and requirements, we in the instrument sensors, lines and structures, etc.
