This product is a multifunctional air quality monitor that detects Carbon dioxide(CO2), Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron#31;sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real time monitoring of Carbon dioxide(CO2), formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.

This detector is suitable for indoor and outdoor air quality, muti-envornmental air quality monitoring for furniture, decorations, cars, and so on.
4.3 inch LCD display, 480*270 pixels, simple and elegant, with high test accurancy, stable performance, with clear and easy to understand digital display, let you know the current air quality at a glance.
Small and portable but with big wisdom, compact, lightweight and cost-effective portable PM2.5 detector to escort your healthy environment.
Built-in lithium battery and usb rechargeable, charge and use, lasting battery life, not afraid of power failure.
On-board fan to draw in ambient air for more accurate real-time results.
Functions: low battery warning, time setting, history record.
Test variables: PM2.5, PM1.0, PM10, HCHO, TVOC, Carbon dioxide(CO2), temperature, humidity, you can get the results you care about.
UNIT: change the temperature unit between Celcius(℃) or Fahrenheit(℉)
Buzzer: use up/down buttons to select whether to turn the alarm buzzer on/off.
Alarm threshold: default factory value alarm threshold levels for HCHO: 0.1mg/m³. When reach 0.1mg/m³, Device alarm sounds. HCHO ideal range: <=0.10mg/m³.
