Buy click: https://www.amazon.com/dp/B01IEULKM4?m=A3ROYT5KW9S5QS&ref_=v_sp_detail_page More products, please pay attention to the official website: www.huafansmart.com 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. Basic parameters: Size：144 mm * 190 mm * 74 mm Weight: about 1130 g Sensor types: electrochemistry method (gas catalytic combustion type, special separately) Destination gas: oxygen (O2), gas (EX), poisonous and harmful gases (CO, H2S, NH3, CL2, etc.) Response time: 30 s or less oxygen; Carbon monoxide 40 s or less;gas or less 20 s;(other) Working pattern: continuous work Working voltage: DC24V Output signal: 485 digital signal Output: four wire (two power cord, two signal lines) T
