Natural Gas Detector with Valve (LPG Alarm)
Main features
1. Adopting high-quality semiconductor calefaction type sensor
2. MCU intelligent supervise control and SMT chip technology
3. Visual and audible alarm function
4. LED numeric display technology, display instant gas leak thickness.
5. Three indicators: POWER, STATE, ALARM
Detecting gas: LPG, natural gas, and coal gas
Power supply: AC100V~AC240V
Power frequency: 50/60Hz
Rated load: <4W
Alarm thickness: LPG: 0.1~ 0.5%; natural gas: 0.1~ 0.3%; coal gas 0.1~ 0.5%
Alarm volume:≥85dB
Working environment: -10ºC~50ºC relative humidity <97%RH
Storage temperature: -25ºC~55ºC
2. Gas leak alarm state:
Under the condition that the alarm enter waiting state, when the alarm detect flammable gas leak:
? when display 0,1,2 in the display window, the STATE LED light green;
? when display 3~9, the STATE LED light yellow., the alarm give slow Di--Di sound when displaying3,4,5 and give quick DiDiDi-- DiDiDisound when displaying 6,7,8,9;
? when display A, the unit alarm, STATE LED light red and ALARM LED light. When the thickness is below presetting level, the alarm resume to the normal working state.
