Xi'an Hua Fan Instrument Co.,Ltd is one of the leading bus-system gas detection transmittermanufacturers and suppliers in China, welcome to buy or wholesale draeger gas ransmitter, draeger gas probe, combustible gas probe, combustible gas ransmitter, toxic and harmful gas probe made in China from us.
Product description
Adopts non-standard agreement or ModBUS protocol for data collection and transmission.
The host round tests various nodes with intelligent background software, and monitoring the gas concentration changes in real-time.
Uses the bus-system, having strong anti-jamming capability, convenient layout and simple wiring.
Also provides an 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 good sensitivity and repeatability.
This instrument uses the embedded micro-controller control technology, simple menu operation, complete functions and high reliability.
