fixed industrial gas detector KB-501X with led display
KB-501X Online Gas detector uses high performance gas sensor and microcontroller and employs SMD technology.
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.
Features1. Advanced sensor; Cast Aluminium housing2. 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).
