Multifunctional Gas Detector CO2 Meter formaldehyde Detector Home PM2.5 Tester indoor Professional Air Quality Monitoring Smog 7 inch Large Screen

Features
Human body induction, intelligent wake-up. 3 meters inductive dynamic monitoring, 60 seconds after the person leaves, the screen will automatically stop and servo detection at any time, intelligent power saving.
Electrochemical method, measuring formaldehyde. The electrochemical sensor effectively eliminates interference from other gases through multi-layer filtration; it effectively captures formaldehyde molecules.
Infrared 3D specular reflection dual-channel optical detection method, dual-optical channel sampling. Using innovative 3D light scattering 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.
Laser scattering particle acceleration measurement method, faster and more accurate. Using innovative light scattering and refraction algorithm, built-in fan gas dust fast convection system, equipped with professional laser detection cavity, AD intelligent signal processing, greatly improving PM 2.5 detection results.
Temperature difference compensation calibration technology. Judge the ambient temperature data and automatically calibrate the test results.
Using ARM chips, most of the world’s Android smartphone processors are produced by ARM, with 32-bit high-speed processing performance, greatly improved computing speed, more accurate detection, and smooth system.
Real-time data monitoring. The hazard degree of harmful gases such as formaldehyde and TVOC is not a constant tracking of the whole process in order to systematically grasp the health of the environment.
