HuiDeonne 4-in-1 Plug-in CO and Natural Gas Alarm Detector with LCD Display

Overview and practical benefits

HuiDeonne delivers a compact plug-in detector that monitors carbon monoxide, combustible gases, temperature, and humidity in real time. UL-tested and designed for everyday living, it provides clear alerts based on sensor readings, helping you stay informed about indoor air conditions without intruding on your space.

Smart sensing you can rely on

This 4-in-1 detector combines reliable electrochemical sensors for CO and natural gas with an accurate LCD readout for temperature and humidity. CO readings range from 0 to 1000 PPM with tiered alert thresholds at 70, 150, and 400 PPM, prompting timely notification. Combustible gas detection spans 0 to 10000 PPM with an alarm at 3000 PPM. Temperature ranges from -32 to 212 F and humidity from 0 to 99% RH.

In daily life, you’ll appreciate seeing live PPM values, plus temperature and humidity, all on one screen to gauge ventilation and comfort at a glance. Key benefits include real-time data that helps you react quickly to changing environments.

Key benefits include:

• Real-time CO and gas readings on a clear LCD
• Temperature and humidity monitoring for room climate awareness
• Audible and visual alerts when thresholds are met
• Plug-in convenience with energy-conscious design

Audible and visual alerts you can trust

When danger thresholds are reached, the detector emits a loud alarm (>85 dB) and flashes a red light to immediately grab attention. This dual alert system is designed to help you notice potential issues even in busy or noisy rooms.
