CO2 Detector — 3in1 portable monitor for carbon dioxide, temperature, and humidity Key benefits Comprehensive monitoring: Measures CO2 concentration, temperature, and humidity in one compact device so you can quickly assess indoor air quality and environmental conditions. Faster, clearer decisions: Realtime readings appear on a colour screen and a colour ring changes with CO2 levels, giving immediate visual cues to ventilate or adjust conditions. Simple operation: Power on/off with a longpress of the 'switch' button. Once on, the detector automatically measures CO2 so you get instant, continuous feedback without complicated setup. Reliable runtime and easy charging: Builtin 1200 mAh lithium battery provides 10–12 hours of continuous use on a full charge. Recharge with a standard charging cable for hassle power. Portable and practical: Lightweight and easy to move between rooms or locations, designed for everyday use in common enclosed spaces. Features and performance 3in1 functionality: Carbon dioxide concentration detector, temperature gauge, and humidity meter in a single portable sensor. Userfriendly interface: Colour display shows CO2, temperature, and humidity values at a glance; dynamic colour ring indicates CO2 levels for quick interpretation. Power and charging: Integrated 1200 mAh lithium battery; rechargeable via a standard charging cable; up to 10–12 hours continuous operation per full charge. Easy control: Turn the unit on or off with a longpress of the 'switch' button; automatic CO2 detection while powered. Practical use scenarios Homes: Monitor living rooms, bedrooms, and kitchens to reduce stuffiness and maintain healthy indoor air quality. RVs: Track CO2, temperature, and humidity while sleeping, cooking, or traveling in confined spaces. Grow tents: Keep close control over CO2, temperature, and humidity to support plant health and optimize growth conditions. What it solves Identifies CO2 levels that can cause drowsiness or poor air quality so you can ventilate promptly. Combines three measurements in one unit, eliminating the need for multiple devices. Portable battery operation and clear visual alerts make it easy to use in places without continuous power. Operation tips Longpress the 'switch' button to turn the detector on or off. Charge before first use to ensure maximum battery runtime. Read values on the colour screen and use the colour ring as a quick indicator of CO2 status. The CO2 Detector delivers straightforward, reliable monitoring of carbon dioxide, temperature, and humidity for homes, RVs, and grow tents—portable, easy to use, and clear to interpret.
