TCB2 series type gas detector, according to different gases can be four or five in one combination, using wireless remote control technology is convenient, high performance sensor combined with sophisticated SMD technology, the instrument has good repeatability, anti humidity interference, using the advantages of long service life, convenient operation etc..
The TCB2 point gas detector uses two or four wire structures, and the monitoring instrument or controller is far away from the field to see the detection results. It is suitable for on-line monitoring of toxic gases and flammable and explosive gases in various environments. The combination of multiple combinations can detect the concentration of various gases visually, and display them separately.
