Specifications
multi gas detector
1 combustion sensor and 3 electrochemical sensors
sound and light and vibration alarm
Multi gas detector is a compact portable gas detector with a large LCD. It can monitor CO, H2S, O2 and combustible gas simultaneously. The instrument features two instant alarms with audio/visual and vibratory indicators, rechargeable battery, and simple use.
Main partameter:
Operating & Storage Environment Temperature: -20°C~55°C (-4F~122F)
Humidity: 5%-95% (Relative humidity non-condensing)
Pressure: 95~110kPa
Alarm Threshold (Two-stage) There may be regional variations, users can set up the value based on practical situation.
Detecting Range Combustible gas: 0~100%LEL (Low/High Alarm Point: 25% LEL/50%LEL)
O2: 0~30% VOL (Low/High Alarm Point: 18.5% VOL/23.5%VOL)
CO: 0~500 PPM (Low/High Alarm Point: 35 PPM/70 PPM)
H2S:0~100 PPM (Low/High Alarm Point: 10 PPM/20 PPM)
Other gas types: referring to the gas parameter list below
Four Transducers Combustible gas: catalytic combustion sensor
O2 / H2S / CO: electrochemical sensor
