factory direct sale fixed combustible and toxic gas detector KB-501
fixed industrial gas detector KB-501
KB-501 fixed gas detector uses high performance gas sensor and sophisticated SMD technology. It has good repeatability,high resistance to humidity-temperature jamming, long working life.
KB-501 can translate the target gas concentration signals into electric current signals or digital signals for outputting and transmitting. It adopted three-wire (4~20mA signals output) and four-wire (RS485 Bus output) system, remotely examine the detection result through the monitor or controller.
Featuresof KB-501
1. Imported Electrochemical sensor;
2. Intrinsically safety circuit design;
3. Three-wire system 4~20mA standard signals output, long distance transmission;
4. RS485 bus output (optional);
5. Possible to connect to DCS system directly;
6. The probe has high sensitivity, quick-response capacity, long working life and short polarization time.
