GRUNDIG RV CO, Propane & Natural Gas Detector. 5-in-1 Plug-in Alarm with Voice Alert & LCD Display & 9V Battery - North American Standard / 4 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 KH168 detects CO, propane, and natural gas before you feel a single symptom — and unlike any alarm that quits when the power does, it keeps watching after the lights go out. Four live readings. A spoken alarm. A 9V battery compartment (battery not included) for the moment the power dies. Ⅰ. Key Highlights 【5-in-1: CO + Propane/Natural Gas + Temperature + Humidity + 9V Battery Backup】 — CO: 0–2,000 ppm, alarms at 150 ppm. Propane & Natural Gas: 0–10% LEL, alarms at just 5% LEL. Plus continuous temperature (1–176°F) and humidity (0–99%) monitoring — and a 9V battery compartment that keeps the unit alive for over 4 hours when mains power fails. Please note: the 9V battery itself is not included. The alarm comes with an empty battery compartment — you simply buy a 9V battery locally and place it in. 【Voice Alert + 85dB Siren + Flashing Red LED】 — Most alarms just beep at 3 a.m. and leave you staring at the ceiling. The KH168 adds a spoken alert — a human voice cuts through deep sleep, headphones, and road noise in a way a beep never will. Backed by a siren with three adjustable volume levels (60 / 70 / 85dB) and a high-contrast red LED that flashes with every alarm. See it even if you can't hear it. 【Alarms at Just 5% LEL — Earlier Warning Than Most】 — Many household alarms don't trigger until 10–25% of the lower explosive limit. The KH168 sounds the alarm at 5% LEL, giving you a wider safety margin to ventilate, shut off the gas, and get everyone outside. Real-time CO concentration, gas concentration, temperature, and humidity on the LCD at a glance. 【9V Battery Compartment — Protection When the Power Dies】 — Plug it in for everyday use; the KH168 runs on AC 110–220V and monitors continuously, year-round. On the rear cover there's a 9V battery compartment — and it arrives empty. No battery is included; you buy one standard 9V alkaline battery yourself and place it in. Leave a battery in the compartment year-round so your backup is always armed, or leave it empty and drop one in only when you need it — both work. When a blackout, tripped breaker, or dead campground pedestal cuts your power, the alarm keeps protecting you for over 4 hours. No charging, no cables, no battery degradation from heat. 【Plugs In Under 60 Seconds — And Adjusts to Your Room】 — No wiring, no tools, no hardwiring into your RV's 12V system. Plug into any standard AC outlet. Three brightness levels and three volume levels let you tune it bright and loud for a hallway, or dim and quiet for a bedroom wall. The plug adapter rotates freely to fit sideways sockets and tight corners. Compact at 4.9 × 2.2 × 2.3 in (124.3 × 56.5 × 57.7 mm). 【Certified & Backed for 2 Years】 — Tested and certified to UL 1484 (residential gas detectors) and UL 2034 (carbon monoxide alarms). One-touch SELF-TEST verifies every sensor, the sounder, and the lights in seconds. Backed by a 2-year warranty — replace, don't repair. 【Ideal For】 — RV, Motorhome, Camper Van, Travel Trailer, 5th Wheel, Truck Cab, Cabin, Home, Bedroom, Kitchen, Basement, Garage, Office, Hotel Room. ⚠️ Important: The KH168 runs on AC power (110–220V) as its normal mode — plug it in and it monitors continuously. This alarm does not come with a battery. It has a 9V battery compartment only; you purchase a standard 9V alkaline battery (GLR61 or equivalent) yourself and place it in the compartment. With a battery installed, the alarm keeps protecting you for over 4 hours during a power outage. Installing a battery is entirely optional for everyday use — but it's your safety net for the moment the power goes out. Ⅱ. Comparison — Why Choose GRUNDIG KH168?
