D MODUN Gas Detector for Home – Natural Gas, LPG & Coal Gas Alarm | PPM LED Display | 85dB | Plug-in

D MODUN Gas Detector for Home – PPM LED DisplayStay one step ahead of danger. The D MODUN gas detector doesn’t just alarm — it shows you the exact gas concentration in PPM on its LED display, giving you real-time visibility into your home’s air quality. From the first trace of a leak to a full alarm, you’re always informed.Key Features PPM digital display: Shows real-time gas concentration (1000–9999 PPM range). Displays "HHHH" when concentration exceeds 9999 PPM. Note: Cannot detect CO or CO₂. Multi-gas detection: Detects natural gas (methane), LPG (propane, butane), and urban coal gas (alkane, olefin, arene). Alarm activates at ≥5% LEL (2500 PPM). 85dB alarm + red strobe: Loud audible alarm and flashing red ALARM indicator activate at threshold. Alarm stops only when gas drops below the threshold. Plug-in, mains-powered: AC 100V~240V adapter included. ABS housing, easy to clean. Power consumption ≤2W. 180-second warm-up: Auto-calibrates on startup. Do not operate during the 3-minute preheat period. Wide application: Kitchens, garages, RVs, restaurants, hospitals, hotels, and gas stations. Alarm Level Guide <1000 PPM: No display, no alarm — safe level. 1000–2499 PPM: Numbers displayed, no alarm — early warning. 2500–9999 PPM (≥5% LEL): Numbers displayed, red strobe + 85dB alarm activated. >9999 PPM: "HHHH" displayed, full alarm — evacuate immediately. Specifications Detecting Gas Natural gas (Methane), LPG (Propane, Butane), Urban coal gas Sensor Type Semiconductor Gas Sensor Alarm Concentration ≥5% LEL (2500 PPM) Preheat Time 3 minutes (180 seconds) Operating Voltage AC 100V ~ 240V, 50/60Hz (DC 5V adapter) Rated Power ≤2W Alarm Volume ≥85dB Material ABS Operating Temperature -10℃ ~ 50℃ Operating Humidity <95% RH Dimensions 30 × 68 × 111 mm How to TestPress and hold the lighter switch at the gas inlet and deflate slowly (do not ignite the lighter). The alarm triggers when gas concentration reaches the threshold and resets once levels drop below the alarm point.⚠️ Do not open a gas stove for testing without professional guidance.
