5 In 1 Formaldehyde Monitor Digital Display Carbon Dioxide Detector Temperature Humidity Monitor for Air Quality Detecting
![]()
5 In 1 Formaldehyde Monitor Digital Display TVOC Detector USB Rechargeable Temperature Humidity Monitor for Home Office Specification: Origin: Mainland China Tips: This product uses a semiconductor sensor with high sensitivity. However, it can only detect, and the data will not be very accurate (called qualitative but not quantitative). It can only detect mixed carbon dioxide, such as carbon dioxide exhaled by the human body, and cannot detect pure carbon dioxide. Description: This machine is equipped with a carbon dioxide sensor and a temperature and humidity sensor, which can measure the concentration of carbon dioxide in the air and the ambient temperature and humidity in real time. The measurement range of carbon dioxide concentration is 400-5000ppm. When the concentration is between 400-800, a green strip is displayed. This means that the concentration of carbon dioxide in the air is low and the air is in a normal state. The green and yellow bands are displayed at the same time between 800 and 1200, which means that the concentration of carbon dioxide is higher. In this environment, it is harmful to the human body, and green, yellow and orange stripes are displayed between 1200 and 1500ppm, indicating that the air is not good for the human body; if it exceeds 1500, the green, yellow, orange and red bands simultaneously show that the concentration of carbon dioxide is seriously exceeded. When it exceeds 5000ppm, it may cause suffocation or even death. You should open the window for ventilation immediately. Button operation: Press once to switch the temperature, twice to turn the sound on and off, 3 times to enter the calibration interface, 4 times to enter the screen-off state (press once to light up the screen) Parameters: CO2 measurement range: 400-5000ppm CO2 measurement accuracy: ±150PPM Temperature measurement range: 0-50°C Temperature measurement accuracy: ±1°C Humidity measurement range: 0%-99%RH Humidity measurement accuracy: ±2%RH HCHO: 0-0.6mg/m³ TVOC: 0 -2.0mg/m³ Screen size: 2.8 inches Screen type: TFT-LCD Screen material: glass Casing material: ABS Screen resolution: 240*240 Response time: <1s Working voltage: 5V/1A adapter charging (Type-C interface) Maximum power: charging current 600mA Powered by 3.7V lithium battery Battery capacity: 1200mAh Battery type: lithium battery Charging method: USB Charging time: about 1 hour Product size: about 90.00x70.00x35.00mm/3.54x2.76x1.38inch
