Feature

●▶Built-in a calculator as a reference for remove hcho and haze, an ideal multifunction testing tool to monitor the air quality with indicate the hcho/pm2.5 pollution level, a safeguard for family health. If exceed standard, alarm prompt.
●▶4.3 inch LCD display, 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.
●▶Test variables: PM2.5, PM1.0, PM10, HCHO, TVOC, Carbon dioxide(CO2), temperature, humidity, you can get the results you care about. Low battery warning, time setting, history record. Change the temperature unit between Celcius(℃) or Fahrenheit(℉)
●▶Alarm threshold: default factory value alarm threshold levels for HCHO: 0.1mg/m³. When reach 0.1mg/m³, Device alarm sounds. HCHO ideal range: less than 0.10mg/m³. use up/down buttons to select whether to turn the alarm buzzer on/off.
●▶Built-in lithium battery and usb rechargeable, charge and use, lasting battery life, not afraid of power failure. Suitable for indoor and outdoor air quality, muti-envornmental air quality monitoring for furniture, decorations, cars, and so on.


Description

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 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.
