▶Features：
👍 Multifunctional Monitoring: Our 7 in 1 indoor air quality monitor provides accurate readings in a wide variety of key air quality metrics; temperature in both Fahrenheit and Celsius, humidity level, formaldehyde concentration (HCHO), total volatile organic compounds (TVOC), multiple levels of particulate matter (PM1.0, PM2.5 and PM10),Ozone(O3).
👍 Advanced Fan and Sensors: This air quality tester is equipped with 2 high grade sensors; the 1st of which is a laser sensor to measure dust particles and the 2nd of which is an electrochemical semiconductor sensor to measure formaldehyde and natural or synthetic organic compound levels; An intake fan is built in to draw in ambient air for accurate and real-time monitoring of air pollution, temperature, humidity and particulate matter.
👍 Total Awareness: Formaldehyde is a colorless gas and toxic compound used in many household products such as plywood, glues, paper coatings and some insulation materials;for example, new or remodeled homes can retain a higher concentration of formaldehyde for 2 years, similar levels to heavy traffic; have peace of mind by always knowing the level of this toxic compound in the air, similarly with total volatile organic compounds (TVOC) which are a combination of VOCs of varying harmfulness.ess.
👍 Portable and Easy Operation: The indoor air quality meter is very intuitive and easy to use, with 3 choices of measurement display based on preference; the small and lightweight device comes with a rechargeable lithium battery rated at 1200 mAh for a high level of portability; in addition, at the back of the unit is a stand for easy placement.
👍 Feature Rich: Many features are included with this home air quality detector such as an alarm for dangerous levels of formaldehyde, which can be configured; historic logs are kept for reference and can be cleared at any time; interface changes such as the brightness, style or screen type are available; lastly, the sensor can be calibrated within the calibration menu.
Description:
This product is a multifunctional air quality detector that detects Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Ozone(O3),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 formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, Ozone(O3),temperature, and humidity on its digital LCD display.
