Feature
●A compact CO2 concentration measuring device so you can see when ventilation at a glance
●Digital display allows you to monitor carbon dioxide concentration, temperature and humidity in real-time, allowing you to see the air condition and know when to ventilate
●400-5000ppm changes numerical value and color display depending on the carbon dioxide concentration
●It can be used in a variety of locations, and can be expected to lower risk by measuring CO2 concentrations
●Temperature measurement range: -10 - 60 °C (±2 °C); Humidity measurement range: 5 % - 99 % RH (±5 % RH); Standby time: approx. 9 hours (Input charging): DC 5 V (Size): 3.7 x 2.8 x 1.7 inches (93 x 72 x 42 mm)

Description
Precautions for Use: Do not use for anything other than the intended purpose. Please do not place this product in a location that is within reach of small children. ● Use built-in lithium battery, standard DC-5V charger. If the magnet is placed close to the magnetic tape, magnetic card, ticket or watch, the magnetic record may be destroyed or magnetized and unused. Please do not fill the air inlet and exit in order to avoid the deviations of the numerical value during use. ● In dusty environments, the air quality is poor, so please do not use it frequently to prolong its life. Please do not use in places with high temperatures, high humidity, or near strong magnetism, to avoid inaccurate values, or to avoid damage to the internal circuit of the device. ● Use in temperatures ranging from 0 DegreeC to 40 DegreeC. ● Store devices and accessories within a temperature range of -20 DegreeC to 55 DegreeC. If the ambient temperature is too low or too high, it may cause it to malfunction. ● Do not use pins or other sharp objects on the air outlet or charging port to prevent damage.
