Product selection, detection range

SFD - 600 II gas transmitter naming method is as follows:

A, "SFD" representative "suofuda company";

B, “600II” means on site display gas detector which can output 4-20 mA signal ; "600" (BZ) Detector has a pair of 24 VDC / 0.5 A switch quantity output, and the SFD - 200 live sound and light alarm can be attached..

C, left after the "600 ii" for 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 of the range, please refer to "chameleon" products.
