This portable carbon monoxide detector can monitor carbon monoxide concentration, temperature, and humidity in real time. Its design balances ease of use and energy efficiency, and it supports fast charging.

Dual Temperature Display, Audible and Visual Alarm

Adjustable Threshold, Long Battery Life
In underground mines, residual carbon monoxide after blasting can be monitored to prevent poisoning and explosion risks; in chemical workshops, carbon monoxide leaks can be detected in real time to ensure production safety; in underground garages and tunnels, CO concentrations from vehicle exhaust can be monitored to prevent poisoning; and during fire rescue operations, it can be used for detection at fire scenes and in confined spaces to protect the safety of rescue personnel.

Q1: Where should a carbon monoxide detector be installed?
A1: It is recommended to install one near each bedroom and on each floor of the house. The best location is on a wall or ceiling, 1.5-2 meters above the ground, away from doors, windows, fans, or HVAC vents.
Q2: Do I need a carbon monoxide detector if I already have a smoke alarm?
A2: Yes, you must. Smoke alarms cannot detect colorless and odorless carbon monoxide gas. They have different functions, but are both essential for home safety and are indispensable. There are also combination detectors on the market that combine the functions of both.
Q3: What should I do if the detector alarms?
A3: Immediately evacuate to a place with fresh air outdoors, turn off the gas supply (e.g., close the gas valve), do not touch any electrical switches, and call emergency services or the gas company for help. Return only after a professional has checked and confirmed it is safe.
Tips: What do the red, yellow, and green indicator lights on the device mean?
The green indicator light primarily displays the device's battery level, making it easy to check the remaining power. A flashing red indicator light indicates a carbon monoxide hazard alarm has been triggered. The yellow light, along with other indicators, displays the device's operating status; the lighting effects are clear and easy to understand.
