Vilfet 4-in-1 Carbon Monoxide & Natural Gas Detector | Plug-in with Dual Alarms

All-in-one protection for your space

The Vilfet 4-in-1 Carbon Monoxide and Natural Gas Detector combines essential sensing with a clear, real-time view of your environment. This compact plug-in device monitors CO, natural gas, temperature, and humidity, delivering quick, actionable information without the need for extra apps or gadgets. It’s designed to fit seamlessly into living rooms, kitchens, bedrooms, and even small travel spaces like RVs.

4-in-1 detection with fast alerts

Two reliable sensors work in tandem to help you stay informed. CO readings range from 0 to 2000 PPM, while natural gas readings go from 0 to 10% LEL. When a potential issue is detected, the detector responds with a loud alarm and a flashing red light, providing immediate, straightforward notice even from across a room.

• Dual alarms: audible ≥85 dB and visual flashing red light for rapid awareness
• Independent sensors support faster, more accurate detection of gas events

Live readings at a glance

The full-color LCD presents CO, natural gas, temperature, and humidity readings in real time. This makes it easier to observe how readings change during cooking, heating, or weather shifts, and to compare day-to-day variations.

• CO range: 0–2000 PPM; Gas range: 0–10% LEL for broad visibility
• Clear numbers help you interpret environmental changes quickly

Versatile placement and simple upkeep

Designed for versatility, this detector suits homes, RVs, hotels, kitchens, and more. Its plug-in design minimizes clutter, while a low standby power draw (< 2 W) supports energy-conscious use. Durable sensors are built for long life with fewer replacements.

• Plug-in operation compatible with AC 110–220 V
• Low standby power helps reduce energy waste

Practical setup tips

For best results, remove the protective film before use, plug in, and allow about 180 seconds for calibration. Use the test button to confirm alarm functionality, then wait roughly 30 minutes for stable humidity and temperature readings. This keeps the device ready for everyday use.
