Production introduction
Economical and spot display gas detector of GQB-200II (electrochemistry): importing sensor and integration module design; extensive used for refinery and chemical plant vulnerable to toxic gases or toxic gas leakage of places and continuously detecting these places. The safety monitoring instruments to protect personal safety and factory. Transfering the concentration of combustible or toxic gas to 4-20mA current signal and work together with all kinds of gas alarms we produced.
