SP-2104Plus is a fixed, intelligent gas detector that measures different gases depending on the sensor installed. It is housed in an explosion-proof structure and uses an intrinsically safe design for electrochemical (EC) sensor. It operates on 12 to 28VDC for EC, and provides an analog (4-20 mA) signal output. At the same time, LED display, optional relays and RS485 output provide flexible configuration. Based on its powerful intelligent process platform and "smart" sensor technology, it supports multiple gases detection, multiple ranges and resolutions, such as CO, H2S,O2, Cl2,NH3,SO2,HCN,NO,NO2
,PH3,ClO2, ETO ,HCl,HF and so on.
