Description
Portable air quality monitor can detect the formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), particulate matter (PM2.5/PM1.0/PM10) in the air as well as temperature and humidity, and also show you air quiality index (AQI) on the LCD display. Low price and high accuracy, it is an ideal testing tool to safeguard your health in the house/office/car.
Features
- Support various test including PM2.5/PM1.0/PM10, formaldehyde, TVOC, AQI, temperature and humidity
- 2.8″ color LCD display, 320*240 pixels, easy to read.
- The air monitor has 4 different interfaces, user-friendly.
- Adopting independent sensors, and high-speed RM processor, fast response and accurate detection.

Product Introduction
Applications
Tips: Operating Principle of Air Quality Monitor
Air quality monitor is a kind of meter that can detect formaldehyde, PM2.5, TVOC, temperature and humidity in real time. It is compact, light, exquisite and portable. The air quality monitor are equipped with independent sensors. Through the sensors inside, the pollutant concentration can be accurately measured and the air quality index AQI can be calculated. When the concentration exceeds the limit, the alarm will be given.
The air quality monitor detects the signal of the front-end formaldehyde sensor, PM2.5 sensors, TVOC sensor and temperature and humidity sensor, enlarging the weak signal sensors through the operational amplifier, removing noise interference by the filter circuit, and then through the AD sampling and the high precision processor calculation, and transfer it into the pollutant density value, and display it on the LCD screen.
