GRUNDIG RV CO, Propane & Natural Gas Detector — 4-in-1 Plug-in Alarm with LCD Display - White / British Standard / 2 units

GRUNDIG: 80 Years of Automotive Engineering & Precision Since 1945, Grundig has stood for German precision engineering. From the 1951 Autosuper 248 to today, we bring German-engineered safety and convenience to every drive — car, RV, and beyond. About GRUNDIG RV CO, Propane & Natural Gas Detector Your RV's furnace, stove, water heater, and generator all produce carbon monoxide. A single propane leak can fill your RV in minutes. Parked at a campground with natural gas? That's a third threat. CO is odorless and invisible — you won't know something's wrong until symptoms hit. By then, it's often too late. The GRUNDIG SR-907 detects CO, propane, and natural gas before you feel a single symptom. One device. Three deadly gases. Zero excuses. Ⅰ. Key Highlights 【Detects CO, Propane & Natural Gas】 — CO: 0–1,000 ppm, UL 2034 certified alarm thresholds. Propane & Natural Gas: 0–10,000 ppm, triggers within 3 minutes at dangerous levels. 【85dB Siren + Flashing Red LED + LCD Display】 — loud enough to cut through your rooftop A/C. See the alarm even if you can't hear it. Real-time CO level, temperature, and humidity at a glance. 【Electrochemical Sensor + One-Touch Self-Test】 — Press TEST for a full diagnostic in seconds. 5–7 year lifespan. Yellow light tells you when to replace. Mute button silences false alarms; auto-resumes in 6 minutes if danger persists. 【Plugs in Under 60 Seconds】 — no wiring, no batteries, no tools. Plug into any standard US AC outlet. Fits flush against the wall, won't block your second outlet. Anti-glare acrylic lens keeps the display readable from any angle. Compact at 4.1 × 2.4 × 2.4 in, just 3.5 oz. 【Ideal For】 — RV, Motorhome, Camper Van, Travel Trailer, 5th Wheel, Cabin, Home, Kitchen, Garage. ⚠️ Important: The SR-907 requires AC shore power or a generator. It does not run on your RV's 12V battery. For boondocking, pair it with any portable power station — it draws less than 1 watt. Ⅱ. Comparison — Why Choose GRUNDIG SR-907?

What's in the Box 1 × GRUNDIG SR-907 4-in-1 CO, Propane & Natural Gas Alarm with Temperature & Humidity Monitor 1 × User Manual Ⅴ. FAQ Q1: What gases does the SR-907 detect?It detects Carbon Monoxide (CO), Propane, and Natural Gas (Methane) — the three most critical gas hazards for RV owners. Q2: Will it go off every time I cook?No. The SR-907 uses an electrochemical sensor — not the cheaper semiconductor type — which means far fewer false alarms. Normal cooking fumes won't trigger it. It only alarms when gas concentrations reach genuinely dangerous levels. Q3: Does it need batteries?No. The SR-907 is powered directly from any standard AC outlet (90-240V, 50/60Hz). Note: the unit requires shore power or a generator to operate — it does not run on your RV's 12V battery system. For boondocking, pair it with any portable power station (Jackery, EcoFlow, Bluetti) — it draws less than 1 watt. Q4: What is the CO measuring range?0 to 1,000 ppm, with alarm thresholds aligned with UL 2034 standards. Q5: What about propane and natural gas? What is the range?0 to 10,000 ppm, with a response time of ≤3 minutes at concentrations ≥3,000 ppm. Q6: Can I use it in the US?Yes! The SR-907 comes with US-compatible pins and is FCC certified. It operates on standard US 120V/60Hz power. Q7: How loud is the alarm?Over 85 decibels at 1 meter (3.3 ft). Q8: What does the yellow light mean?A flashing yellow light indicates the sensor has reached the end of its service life (typically 5-7 years) or a device fault. Replace the unit when you see the yellow light. Q9: How do I test the device?Press the TEST button once. The unit runs a full self-diagnostic and confirms all sensors and alarms are working. Q10: I've heard CO rises and propane sinks — can one detector really cover both? CO is slightly lighter than air and tends
