85 dB Gas Detector, Natural Gas Alarm, LPG, Propane, Plug-in Alarm with Digital Display for Home

【Gas Detector Operation】 -- The UZOPI U gas detector can detect leaks of dangerous and flammable gases, such as natural gas, town gas, and LPG. It cannot detect toxic gases such as CO. Note: The gas sensor needs to warm up for 3 minutes after being plugged into the outlet and the power switch; the light will remain on.
【Audible Alarm & LED Digital Display】 -- The number indicates the concentration. The number 0 indicates a normal condition. The gas alarm detector displays the number 1-9 when flammable gas is detected. The gas alarm will sound at 85dB when the concentration is > 3. It displays "A" when the concentration is > 9. Alarm mode: audible and visual alarm. Alarm indicator: flashing red; Error indication: The yellow indicator light is on.
【Energy Saving & Durable】 -- These gas detectors adopt the European standard plug-in design & energy-saving design. Power consumption is 3W, and they are made of high-quality, flame-retardant ABS plastic, making them very durable and practical.
【Testing Method】 The methane detector slowly releases air. When the concentration reaches the default value, an alarm is triggered until the ambient gas volume falls below the alarm point. Note: Do not open the lighter while releasing gas. It takes approximately 2 to 3 minutes for the system to warm up. Meanwhile, the gas test is invalid.

How can I test if this works After receiving the product?

1. When the detector enters normal detection mode, place an unlit lighter near the detection zone opening.

2. 1 to 5 seconds later, the detector's internal sensor will detect it. When the concentration reaches the standard, an alarm will sound.

3. Once the lighter is removed, the alarm will stop as soon as
