Product Description:
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 node acquisition collects and detects the gas concentration on the spot. with an optional alarm lamp, the h2s gas detector will make audible&visual alarm when gas concentration exceed a preset alarm value. The h2s sensor can also connected to a gas controller
