fixed toxic industrial gas detector KB-501

Industrial gas detector fixed toxic gas detector Intrinsically safety circuit design ISO9001:2000 certificate

 fixed toxic 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.

Features of KB-5011. 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.
