From the 1951 Autosuper 248 to today, we bring German-engineered safety and convenience to every drive — car, RV, and beyond.\u003c\/p\u003e\n\n\u003ch2\u003eAbout GRUNDIG RV CO, Propane \u0026amp; Natural Gas Detector\u003c\/h2\u003e\n\u003cp\u003eYour 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.\u003c\/p\u003e\n\u003cp\u003eThe GRUNDIG KH885 puts four live readings on one screen — \u003cstrong\u003eCO, combustible gas (propane \u0026amp; natural gas), temperature, and humidity\u003c\/strong\u003e — and tells you out loud the moment something is wrong. \u003cstrong\u003eFour readings. One screen. A spoken alarm you won't sleep through.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eⅠ. Key Highlights\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e【4-in-1: CO + Propane\/Natural Gas + Temperature + Humidity】\u003c\/strong\u003e — Carbon monoxide: 0–2,000 ppm with a time-weighted alarm response. Combustible gas (propane \u0026amp; natural gas): 0–10% LEL, alarming at just 5% LEL. Plus continuous temperature (1–176°F) and humidity (0–99% RH) monitoring. Four sensors, four live numbers, one screen — no app to install, no second device to buy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Voice Alert + ≥85dB Siren + Flashing Red LED】\u003c\/strong\u003e — Most alarms just beep at 3 a.m. and leave you staring at the ceiling. The KH885 adds a \u003cstrong\u003espoken alert — \"Gas leak detected. Please pay attention.\"\u003c\/strong\u003e — a human voice cuts through deep sleep, headphones, and road noise in a way a beep never will. Backed by a \u003cstrong\u003e≥85dB\u003c\/strong\u003e high-frequency siren with strong penetration and a high-contrast red LED that flashes with every alarm. See it even if you can't hear it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Real-Time Monitoring \u0026amp; Display — Peace of Mind You Can Read】\u003c\/strong\u003e — Most alarms only tell you something is wrong. The KH885 tells you \u003cem\u003ehow wrong\u003c\/em\u003e: live CO in ppm, gas in % LEL, temperature in °F, humidity in % RH. Watch the numbers climb while you ventilate — and watch them fall before you go back inside. That visible confirmation is what most alarms can't give you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【High-Definition Colour Screen, Crisp Readings】\u003c\/strong\u003e — A bright, high-contrast display keeps all four readings legible at a glance — even from across the room, even in a dark hallway at 3 a.m.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Time-Weighted CO Response — Fast Where It Counts】\u003c\/strong\u003e — CO danger depends on concentration \u003cem\u003eand\u003c\/em\u003e exposure time, so the KH885 follows a time-weighted curve: \u003cstrong\u003e50 ppm → alarms within 60–90 minutes · 100 ppm → within 10–40 minutes · ≥200 ppm → within 1 minute.\u003c\/strong\u003e Low levels give you time to act; a dangerous concentration trips it almost instantly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Alarms at Just 5% LEL — Earlier Warning Than Most】\u003c\/strong\u003e — Many household alarms don't trigger until 10–25% of the lower explosive limit. The KH885 sounds the alarm at \u003cstrong\u003e5% LEL\u003c\/strong\u003e, giving you a wider safety margin to ventilate, shut off the gas, and get everyone outside.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Smart Fault Detection — A Dead Sensor Never Pretends to Be Safe】\u003c\/strong\u003e — A dedicated \u003cstrong\u003eyellow FAULT indicator\u003c\/strong\u003e tells you when the unit itself needs attention. A steady \u003cstrong\u003egreen POWER light\u003c\/strong\u003e confirms it's monitoring, and one press of \u003cstrong\u003eSELF-TEST\u003c\/strong\u003e runs a full check of sensors, sounder, and indicators. Test it weekly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Plugs In Under 60 Seconds — Wide Voltage, Low Power】\u003c\/strong\u003e — No wiring, no tools, no hardwiring into your RV's 12V system. Plug into any standard AC outlet (110–220V). An intelligent microprocessor keeps readings stable while a low-power design and \u003cstrong\u003e\u0026lt;120mA alarm current\u003c\/strong\u003e keep running costs negligible — leave it on duty year-round. Compact at 2.44 × 3.82 × 2.05 in (62 × 97 × 52 mm) and just \u003cstrong\u003e98 g (3.5 oz)\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【US \u0026amp; EU Plug Versions — Backed for 2 Years】\u003c\/strong\u003e — Choose the North American plug or the European plug to match your region; same unit, both running on AC 110–220V. Backed by a \u003cstrong\u003e2-year warranty — replace, don't repair\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e【Ideal For】\u003c\/strong\u003e — RV, Motorhome, Camper Van, Travel Trailer, 5th Wheel, Truck Cab, Cabin, Home, Bedroom, Kitchen, Basement, Garage, Office, Hotel Room, Apartment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Important:\u003c\/strong\u003e The KH885 runs on \u003cstrong\u003eAC power only (110–220V)\u003c\/strong\u003e and has \u003cstrong\u003eno battery compartment\u003c\/strong\u003e — it monitors whenever it has mains power. For RV use, plug it into shore power or an inverter-fed outlet so protection stays continuous. Because \u003cstrong\u003eCO rises\u003c\/strong\u003e and \u003cstrong\u003epropane sinks\u003c\/strong\u003e, one unit in one position can't cover both zones — we recommend running \u003cstrong\u003etwo: one high, one low\u003c\/strong\u003e (see FAQ Q11).\u003c\/p\u003e\n\n\u003ch2\u003eⅡ.

FAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: What gases does the KH885 detect?\u003c\/strong\u003e\u003cbr\u003e\nIt detects Carbon Monoxide (CO), Propane (LPG), Natural Gas (Methane), and other combustible gases — plus continuous temperature and humidity monitoring. Four live readings on one screen.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ2: Does it detect propane?\u003c\/strong\u003e\u003cbr\u003e\nYes. The KH885 detects propane (LPG) as well as natural gas, alongside carbon monoxide.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: Does it show the actual numbers, or just beep?\u003c\/strong\u003e\u003cbr\u003e\nIt shows the numbers. The LCD displays live CO in ppm, combustible gas in % LEL, plus temperature and humidity — so you can watch levels rise and fall in real time instead of guessing from a flashing light.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ4: Will it go off every time I cook?\u003c\/strong\u003e\u003cbr\u003e\nNo. The KH885 only alarms when gas concentrations reach genuinely dangerous levels — its threshold is 5% LEL, a point well above normal cooking fumes. It also uses a time-weighted CO response, so brief low-level readings won't trigger it while a real danger trips it fast.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ5: What is the CO alarm response?\u003c\/strong\u003e\u003cbr\u003e\nA time-weighted curve: \u003cstrong\u003e50 ppm\u003c\/strong\u003e alarms within 60–90 minutes, \u003cstrong\u003e100 ppm\u003c\/strong\u003e within 10–40 minutes, and \u003cstrong\u003e200 ppm or more\u003c\/strong\u003e within one minute. Short exposure to low levels won't cause false alarms; a dangerous concentration trips it almost instantly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ6: What about propane and natural gas? What is the range?\u003c\/strong\u003e\u003cbr\u003e\n0 to 10% LEL, with the alarm triggering at just 5% LEL — an early-warning threshold that gives you more time to act than most household alarms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ7: What does the voice say?\u003c\/strong\u003e\u003cbr\u003e\nIt speaks one clear, simple alert: \u003cstrong\u003e\"Gas leak detected. Please pay attention.\"\u003c\/strong\u003e A human voice pulls your attention far better than a beep — especially when you're asleep or the room is noisy. It deliberately doesn't announce which specific gas triggered the alarm; for that, just glance at the LCD, which shows the live CO level, gas level, temperature, and humidity, with the red ALARM indicator lit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ8: How loud is the alarm?\u003c\/strong\u003e\u003cbr\u003e\n≥85 dB, with a sharp high-frequency tone designed for strong penetration — loud enough to cut through a running generator, road noise, and deep sleep.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ9: Is it battery powered?\u003c\/strong\u003e\u003cbr\u003e\nNo. The KH885 runs on \u003cstrong\u003eAC power (110–220V) only\u003c\/strong\u003e and has no battery compartment — it monitors whenever it has mains power. For RV use, plug it into shore power or an inverter-fed outlet so protection stays continuous.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ10: Can I use it in the US?\u003c\/strong\u003e\u003cbr\u003e\nYes. A North American plug version is available, and the unit operates on standard US household power. A European plug version is also available for other regions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ11: I've heard CO rises and propane sinks — can one detector really cover both?\u003c\/strong\u003e\u003cbr\u003e\nCO is slightly lighter than air and \u003cstrong\u003erises\u003c\/strong\u003e, so it tends to sit at breathing height. Propane is heavier than air and \u003cstrong\u003esinks\u003c\/strong\u003e, so it collects near the floor. That's physics — and one alarm sitting in a single spot simply can't watch both zones equally well.\u003cbr\u003e\u003cbr\u003e\n\u003cstrong\u003eOur recommendation: buy two, and place one high and one low.\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003ePlug one into a higher outlet\u003c\/strong\u003e (bedroom or living area) — this is your \u003cstrong\u003eCO coverage\u003c\/strong\u003e, watching the air you breathe while you sleep.\u003cbr\u003e\n• \u003cstrong\u003ePlug one into a lower outlet\u003c\/strong\u003e (near the galley, stove, or propane locker) — this is your \u003cstrong\u003epropane coverage\u003c\/strong\u003e, catching a leak right where the gas actually pools.\u003cbr\u003e\u003cbr\u003e\nUp top and down low — that's when you're genuinely covered. Two units still cost less than a single hardwired RV detector that only watches one gas. Many of our customers do exactly this, and sleep better for it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ12: Can I use it in my RV?\u003c\/strong\u003e\u003cbr\u003e\nYes — it runs on standard AC 110–220V, so it works on shore power or plugged into an inverter-fed outlet in your motorhome, travel trailer, fifth wheel, camper van, or truck cab. Keep in mind there's no battery compartment, so it monitors whenever it has AC power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ13: Why did the reading look off when I first plugged it in?\u003c\/strong\u003e\u003cbr\u003e\nThe unit preheats for \u003cstrong\u003e180 seconds\u003c\/strong\u003e after power-on; the green POWER light confirms it's monitoring once warm-up is complete. Give it those three minutes before reading the numbers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ14: How do I know it's still working?\u003c\/strong\u003e\u003cbr\u003e\nThree ways: the green POWER indicator stays on during normal operation; a yellow FAULT indicator lights if the unit detects an internal problem; and pressing SELF-TEST runs a full check of sensors, sounder, and indicators. Test it weekly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ15: What should I do when the alarm sounds?\u003c\/strong\u003e\u003cbr\u003e\nTurn off the gas appliance and shut off the fuel supply, move everyone to fresh air, and don't re-enter until the source is found and fixed. If it sounds again within 24 hours, have a qualified technician inspect your gas appliances.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ16: What if something goes wrong?\u003c\/strong\u003e\u003cbr\u003e\nEvery KH885 is backed by a \u003cstrong\u003e2-year warranty\u003c\/strong\u003e.
