7 Inch Color Screen Carbon Dioxide CO2 Detector Professional Household PM2.5 Formaldehyde Analyzer Air Quality Monitor Intelligent Desktop Thermometer Hygrometer Human Body Induction Real-time Monitor

We all know that air is an indispensable part of our lives. The quality of air is affecting our body and mind, but the air is colorless and tasteless，we can't measure it with the eyes. At this time, we need an air tester to help us monitor the air quality.

Features:
3.0 meters induction dynamic monitoring, 60 seconds automatic screen off after leaving. Servo detection at any time, intelligent power saving.
Using 3D optical dispersion and refraction algorithm, built-in dual-channel optical detection channel, professional multi-layer gas filtering anti-interference technology, AD intelligent signal processing, greatly improving the reliability of carbon dioxide detection.
Using optical dispersion and refraction algorithm, built-in fan gas and dust rapid convection system, equipped with professional laser detection chamber, AD intelligent signal processing, greatly improving PM2.5 detection results.
Using digital temperature and humidity sensor, the 7-inch large screen display is clear at a glance, it is a intelligent desktop temperature and humidity meter.
Temperature difference compensation calibration technology, judge the ambient temperature data, automatically calibrate the test results.
Using ARM chip, 32-bit high-speed processing performance, the calculation speed is greatly improved, the detection is more accurate, and the system is smoother.
Large cavity, convection air duct, spiral air flow, faster sampling, more sensitive and reliable measurement.
24-hour data real-time monitoring.
Intelligent hazard alarm system, with adjustable alarm threshold, can meet the different needs of families, schools, shopping malls and other environments.
