CO2 Detector, Portable NDIR CO2 Monitor, Has Metal Hooks Air Quality Monitor, 3 in 1 Carbon Dioxide Detector with CO2 Alarm/Digital Thermometer/Humidity Monitor/, for Home Caravan Indoor Outdoor Tent

• [Multifunctional CO2 Tester]: This 3-in-1 carbon dioxide monitor with a high-quality infrared NDIR sensor, high measurement accuracy and fast response time, can detect carbon dioxide concentration in real time and monitor indoor and outdoor humidity and temperature. The CO2 detection range is 400-5000 PPM. In addition, it can also monitor air temperature (0-50°C) and humidity (0-99% RH).

• [Mini Air Quality Monitor]: Mini CO2 detector with a hook (2.87*2.87*0.71 inch), small and portable, can be carried around as a decorative item to check the air quality anytime and anywhere. Intelligent warning system, high-quality IR NDIR sensor, multiple anti-interference.

• [CO2 Concentration Alarm]. Built-in high-performance carbon dioxide sensor with more professional infrared optics technology for accurate and fast carbon dioxide detection. If the CO2 in the air exceeds 1000 PPM, people feel uncomfortable and work/study less efficiently. In crowded places, where CO2 levels rise, it is important to keep rooms ventilated during viruses. With our CO2 meter, an audible alarm will be sounded immediately when the CO2 in the air exceeds 1200 PPM.

• [HD LED Screen]. The digital smart CO2 monitor with a backlit full-color LCD screen is designed to make it easier for you to read the data. Eye protection with 4 different color bars on the screen representing different CO2 levels (green, yellow, orange and red) for quick identification of the air quality around you. The carbon dioxide sensor must only be calibrated in a ventilated area for 5-10 minutes to start working. Please allow up to 35 seconds to react to changes in air quality.

• [ Portable and Long Battery Life ]: This portable CO2 monitor has a built-in 1200 mAh rechargeable battery that takes only 2.5 hours to charge and can work continuously for 8 hours, supports USB charging and has a low battery indicator. You can check the air quality from anywhere or have the device continuously monitored at a specific location. Suitable for home, office, school, travel, camping, caravan, car, hotel, kitchen, bedroom, medical room, party, agriculture, indoor garden, etc.
