fixed toxic industrial gas detector KB-501X LED display
fixed toxic industrial gas detector KB-501X LED display
KB-501X Online Toxic Gas detector uses high performance Electrochemical gas sensor and microcontroller and employs SMD technology. It has good repeatability,high resistance to humidity-temperature jamming, long performance life and simple operation.
KB-501X can translate the detected 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.
KB501X 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.
Features1. Advanced Electrochemical sensor; Cast Aluminium housing/ shell 2. Intrinsically safety circuit design;3. High brightness LED digital display, clear and direct;4. Three-wire system 4~20mA standard signals output;5. Possible to connect to DCS system directly;6. Two-stage (low/high) alarm double switching value output;7. The probe has following advantages: high sensitivity, quick-response capacity, long performance life and short polarization time.8. Function of infrared remote control operation (remote-control is optional units).
