Usb Rechargeable Air Quality Tester Monitoring Co2 / Tvoc / Hcho / Temperature / Humidity Intelligent Alarm Thermometer Hygrometer With Temperature Compensation Calibration

Features: 5-in-1 Monitoring: including CO2 / TVOC / HCHO / temperature / humidity monitoring. With different colors on the digital LED screen to indicate whether the current value is (safety / warning / exceeding the standard). High Performance Chip: accurately capture the weak current generated in the electrochemical reaction process and calculate the measurement results, conversion improving & output efficiency improving & intelligent power saving & service life increasing. Multiple -Interference: based on air convection technology, it adopts scientific multi-angle vents design to achieve fast heat dissipation and more accurate monitoring. Sound & Light Alarm: when the values of CO2 / TVOC / HCHO exceed the standard, it will automatically start the sound and light intelligent alarm. Environmental Protection & Energy Saving: with built-in 1200mAh lithium battery, it can be charged through USB cable to achieve 10 hours standby time and low power prompt function. Wide Application: real-time monitoring, suitable for new car, new house, baby room, children's room, living room, bedroom, school, office, hotel, etc. Specifications: Material: ABS + electronic components Color: White Power Supply: 1 * 3.7V 1200mAh lithium battery Charging Interface: Type-C interface Charging Voltage: 5V Standby Time: 10h Measurement : CO2: 350~2000ppm TVOC: 0.000~2.000mg/ HCHO: 0.000~1.000MG/ Temperature: 0~90℃ Humidity: 0~99%RH Item Size: Approx. 6.7*3.2*9.8cm / 2.64*1.26*3.86in Item Weight: Approx. 141g / 4.97oz Package Size: Approx. 7*4*10cm / 2.76*1.57*3.94in Package Weight: Approx. 220g / 7.76oz Packing List: 1 * Digital Tester 1 * USB Cable 1 * User Manual (English)
