Portable Carbon Monoxide and Carbon Dioxide Detector, 4-in-1 Carbon Monoxide and Carbon Dioxide Monitor with Magnetic Mount, Rechargeable Carbon Monoxide (CO) and Carbon Dioxide (CO) Temperature/Humi

[Portable 4-in-1 Carbon Monoxide and Carbon Dioxide Detector] The portable 4-in-1 carbon monoxide detector monitors current levels of carbon monoxide, carbon dioxide, temperature, and humidity in the air in real time. Equipped with high-precision sensors (10-year lifespan), it detects carbon monoxide concentrations ranging from 0 to 1000 ppm (±10%), the CO concentration range is 4005000 ppm (±(50 ppm + 5%)), the temperature range is 14122°F (±2.7°F) / -1050°C (±1.5°C), and the humidity range is 095% RH (±5% RH). Data is accurate and lag-free, with real-time monitoring.

[Carbon Monoxide LED Indicators and Customizable Alarm Thresholds] The carbon monoxide monitor features a three-level LED indicator based on carbon monoxide concentration: 049 ppm (green flashing = safe), 5099 ppm (yellow flashing = warning), and 1001000 ppm (red flashing = danger). By default, the carbon monoxide monitor will sound an alarm when the concentration reaches 50 PPM. You can double-click the Function Button to customize the carbon monoxide concentration alarm threshold. Note: The device must be on the CO screen before entering the CO customization settings.

[Carbon Dioxide LED Indicators and Custom Alarm Thresholds] The carbon dioxide monitor displays three-level LED indicators based on carbon dioxide concentration: 400699 PPM (green flashing = safe), 7001,499 PPM (yellow flashing = warning), 1,5005,000 PPM (red flashing = danger). By default, an audio alarm sounds when the concentration reaches 1500 PPM. You can double-click the Function Button to customize the CO concentration alarm threshold. Note: The device must be on the CO screen before you can access the CO customization settings.

High-Capacity Battery and Fast ChargingThe MINI 4-in-1 Carbon Monoxide Detector features a built-in 1000mAh lithium battery for extended battery life. It supports QC 2.0, PD 3.0, AFC, USB-C UFP (BC1.2, DCP, CDP, SDP), and other common fast-charging protocols, with charging power ranging from 10 to 65W. When the CO detector has been inactive for 5 minutes, it automatically enters power-saving mode (screen brightness is reduced); you can press the Function Button to turn on the backlight.

[Outdoor Lanyard and Magnetic Mount] The CO2 air quality monitor can be placed anywhere on a flat surface, such as a table in the living room, kitchen, or bedroom. It also comes with a dedicated outdoor lanyard for easy portability during outdoor activities like travel, camping, picnics, and adventures. The back of the CO2 monitor features a magnetic mount, allowing it to be attached to any metal surface, such as household appliances or a car.
