The factory wholesalers the MKRQ901cooking gas leak detector,GAS LPG detector,home security alarm system

Product Overview

The MKANG (MKRQ901) combustible gas detector is a household fire-fighting electronic product that detects whether methane (the main component of CH4 natural gas) and propane (the main component of C3H8 liquefied petroleum gas) exceeds the standard. The product has a strobe warning, live voice, microprocessor control, and support for concentration gas concentration display. When the gas detector is triggered, it will issue a built-in alarm. The detector uses a catalytic combustion sensor that is stable and reliable. It protects the site from flammable gases such as liquefied petroleum gas, natural gas, methane, and the like.



Product Details

Fire-resistant ABS flame retardant material : Ingeniously created to resist high temperature, non-flammable, safer.




The concentration shows at a glance

l The number clearly shows the gas concentration.

l    Time in seconds (s): when the detector is in  pre-heating mode, the countdown time is accurately and intuitively displayed.

l    Identification unit for concentrations exceeding the standard (Δ): when the detector is in detection mode, the identification will light up if the concentration value exceeds the detector range.

l    Concentration display unit (% LEL): when the detector is in detection mode, the concentration values are visually displayed.



Exclusive design patentNo 007009485-0001




High-performance catalytic combustion gas sensor Sensitive, quick alarm, energy saving, long life.



Flashing lights alert : Red flashing is more eye-catching.




Function self-test button : Self-diagnostics for open and short circuit faults in sensor.

l    Green: power indicator light. When the detector is in detection mode, the green indicator light is always on.

l    Yellow: fault indicator light. When the detector is in fault mode, the yellow indicator flickers and sounds "Detector Faulty" every 5 seconds. The indicator stops flickering when optimal and no faults are detected.

l    Red: alarm indicator light. When the detector is in alarm mode, the red indicator light flickers and sounds the "Gas Leakage" prompt. The indicator turns off out when the detector is in normal mode.




Multilingual voice prompts : (Chinese, English, French, German, Italian, Spanish, Turkish, etc.)
