SFD - 600 (BA), naming method (BZ) series gas detector is as follows:

A, "SFD" representative "suofuda company";

B, "600" (BA)means  gas detector can  output 4-20 mA signal without display on site; "600" (BZ) means the Rs485 Bus signal output detector without display on site.The above two kind of Detectors both have  a pair of 24 VDC / 0.5 A switch quantity output, and the SFD - 200 live sound and light alarm can be attached.
C, "600" (BA) or "600" (BZ) left after the first "X" on behalf of gas detection by object, example: "T", "F", "N", "H", "c", "SO2, HF," CL ", "S" represent the general combustible gas, benzene and aromatic gas, ammonia, hydrogen, carbon monoxide, sulfur dioxide, hydrogen fluoride, chlorine, hydrogen sulfide (not list the types of gas, represented by the former).
D, left for the second "X" represents the type of gas sensor, "C" on behalf of catalytic combustion type, "d" for electric chemical formula, "G" on behalf of the solid-state semiconductor type, "I" on behalf of infrared type, "P" on behalf of the photoelectric ion type. Sensor detection range range same as the transmitter with the display.
Such as:

SFD - 600 (BA) SD: 4-20 ma output, hydrogen sulfide, the range of 0-100 PPM, electrochemical sensors
SFD - 600 (BA) CL2D: 4-20 ma output, chlorine gas, range 0 to 10 PPM, electrochemical sensors
SFD - 600 (BZ) TC: RS485 bus signal, combustible gas, range 0-100% LEL, catalytic combustion sensors
SFD - 600 (BZ) : HC, hydrogen, RS485 bus signal range 0-100% LEL, catalytic combustion sensors
SFD - 600 (BA) SO2D: 4-20 ma output, sulfur dioxide, range 0 to 100 PPM, electrochemical sensors
SFD - 600 (BA) FP: 4-20 ma output, benzene and aromatic gases, the range of 0-100 PPM, photoelectric sensors
SFD - 600 (BA) ND: 4-20 ma output, ammonia, 0-100 parts per million, electrochemical sensors
SFD - 600 (BA) CD: 4-20 ma output, carbon monoxide, 0-500 parts per million, electrochemical sensors
SFD - 600 (BA) HFD: 4-20 ma output, hydrogen fluoride, 0 to 10 PPM, electrochemical sensors
SFD - 600 (BA) CO2I: 4-20 ma output, carbon dioxide, 0-100% VOL, infrared sensors
