The series of 485 main line gas detection alarm system adopts non-standard agreement or MODBUS protocol for data collection and transmission.
The intelligent transmitter nodeacquisition collects and detects the gas concentration  on the spot,
The host round tests various nodeswith intelligent background software, and monitoring the gas concentration changes in real-time .
Our product uses the bus-system , having strong anti-jamming capability, convenient layout and simple wiring . At the same time , it also providesan controlling external device (exhaust fan, solenoid valve, etc.) of the switch output.
The detector detects gas concentration with natural diffusion mode, which uses the imported sensors and has a goodsensitivity and repeatability.
This instrument uses the embedded microcontroller control technology, simplemenu operation , complete functions and high reliability .
Bus-system gas detection transmitter adopts aluminum shell material with high strength, heat resistance and corrosion resistance.Our product is suitable for the detection of poisonous and harmful, inflammable and explosive gas in the air and has been widely used in metallurgy, power plant, chemical industry, mine, tunnel, tunnels, underground pipeline and other places, effectively preventing  the happening of the accident.
