一、用途特点MGB—1型光电导通表适用于有瓦斯及煤尘爆炸危险的矿井,以及地面采矿、铁路隧道、军事工程、开山筑路等爆破现场,作为测量电雷管爆破电路的导通情况和爆破后确定瞎炮情况,也适用于检查雷管导通情况,以及测量各种电气回路导通情况(但不能测出回路电阻数值)。光电导通表是以国产59—A 型半导体 First, the use of features MGB-1-type optical conduction table for gas and coal dust explosion hazard mine, as well as ground mining, railway tunnels, military engineering, mountain road and other blasting scene, as the measurement of electric detonator blasting circuit conduction The situation and after blasting to determine blind gun situation, but also applies to check the situation of the detonator conduction, as well as measuring various electrical circuit conduction situation (but can not measure the loop resistance value). Photo-conduction table is a domestic 59-A-type semiconductor
