4 in 1 Upgraded Natural Gas Leak Detector and Carbon Monoxide Detectors, Dual Sensor Gas Leak Detector & Carbon Monoxide Detectors Plug in (Temperature & Humidity) for Home, RV (Black)

4-in-1 Advanced Detection: This upgraded 4-in-1 gas & carbon monoxide detector combines sensors for natural gas, carbon monoxide, temperature, and humidity in a single compact device. Features dual sensors and dual alarms for fast, accurate alerts. Detects CO, coal gas, and more.
Quick Alert with Dual Alarm System: RV carbon monoxide detectors designed with both sound and flashing light alerts, this detector activates when gas levels reach dangerous thresholds (CO ≥ 150PPM or natural gas ≥ 5%LEL). It emits a loud ≥ 85 dB alarm and flashing red light, alerting you and your family instantly in the event of a leak.
Energy-Efficient & Eco-Friendly: Carbon monoxide detectors plug-in design supports 110V–220V AC with ultra-low power consumption (≤ 2W). Built-in electronic sensors offer long-term use without the need for frequent replacements—saving energy and reducing waste for a more sustainable home safety solution.
Clear LCD Display & Versatile Use: Equipped with a full-color LCD screen, this detector clearly displays real-time values of CO (0–2000 PPM) and natural gas (0–10% LEL). Its compact form factor makes it ideal for use in homes, RVs, hotels, kitchens, and cruise cabins without taking up extra space.
Important Setup Instructions: Before first use, remove the protective film from the screen. After plugging in, wait 180 seconds for calibration. Press the test button to check the alarm. For accurate temp and humidity, allow 30 minutes.
