Fixed online gas detector KB-501SG employs advanced Catalytic Combustion or Electrochemical sensor and microcontroller, and SMD technology. It has good repeatability,high resistance to humidity-temperature jamming, long working life and easy operation.
Gas detector 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.
KB501SG is applied to gas safety inspection and alert for industrial working place, such as Petroleum Refinery, Chemical Plants, LPG stations, Boiler Rooms, Gas Stations, Paint Spray Booths, etc.
