SMART Gas Detector/Transmitter(4~20mA) & Explosion Proof

DA-100 detects combustible or toxic gas leakage and transmits standard electric current output signal 4 ~ 20mA to be connected with various controllers such as gas leakage warning device (GMS-1000/1500/2000), PLC, DDC, or MMR for individual or integrated gas monitoring system(controller).

[ Features ]
