online industrial gas detector KB-501SG

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

Industrial gas detector

Fixed online gas detector KB-501SG employs advanced Catalytic Combustion or Electrochemical sensor and microcontroller, and SMD technology. KB-501SG can translate the target gas concentration signals into digital signals for display. Three-wire system 4~20mA electric current signals output, with long-distance transmission and good anti-interference capacity. In addition, it has two-stage alarm function with acoustic and visual signals.
