Product description

What types of gases can our 4-in-1 Natural Gas & Carbon Monoxide Detector detect?

It supports carbon monoxide, methane, LPG, LNG, Fuel, natural gas, fuel, ethane, butane, alcohol, coal gas, gasoline, toluene, kerosene, sewer gas, and other flammable gases.

Why do I need to remove the protective film before using the detector?

Tearing off the protective film can ensure that the numerical display is clearer. There will inevitably be impacts during transportation, which will cause scratches on the protective film (not second-hand goods).

Why Choose 4-in-1 Natural Gas & Carbon Monoxide Detector?

The 4-in-1 detector simultaneously detects natural gas and carbon monoxide, while also displaying temperature and humidity. This comprehensive functionality ensures the health and safety of you and your family, surpassing single-function detectors.

Why does the detector need to warm up for 180 seconds?

Warming up ensures detector’s working properly and accurately.

What should you do when the detector alarms?

Confirm the gas leak source, avoid electrical devices and flames, and ventilate the area. If it’s a natural gas leak, shut off the gas. For a high carbon monoxide alarm, evacuate immediately and call emergency services.

NICGOL 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 & 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 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 temperature and humidity, allow 30 minutes.
