Meter Accurate Testing for PM2.5/PM10/PM1.0/HCHO/TVOC

Air Quality Laser Particle Detector Professional Meter Accurate Testing for PM2.5/PM10/PM1.0/HCHO/TVOC​

Product 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.

Specification

Q: What the test index are include for air quality monitor? A : PM2.5: is main for smog(PM1.0 and PM10 are the same); HCHO: is for formaldehyde; TVOC: is main for benzene,etc Volatile organic compounds; AQI: is for Integrated air quality index. Q: What is the safe range for formaldehyde (HCHO) and TVOC? A : HCHO≤ 0.10mg / m3 TVOC≤ 0.60mg / m3 According to ("indoor air quality standards" GB / T 18883-2002 and GB 50325-2001 Class II civil construction). Q: What is the standard range for PM2.5? A: Good 0~12 Medium 12~35 safe value 35~70 Unhealthy more than 70 Q: What is the standard range for CO2 ? A: Excellent <=1000 ppm Good 1001-3000 ppm Poor 3001-5000 ppm Q: Why does the products make a sound when working? A : As PM2.5 detection need to collect a lot of mobile air, the inner fan needs strong operation to ensure accurate detection. Q: How much range of detection of formaldehyde concentration detector,how many square meters? A : Test area≤ 50m3, room should be set 1~3 testing points; 50m3 ≤ Test area≤ 100m3, room should be set 3~5 testing points; ≥100m3, the points should more than 5 ponits. Testing points is on a diagonal or plum blossom evenly distributed, would more better. The height of the sampling point: in principle,consistent with the human breathing. Relative height of 0.5m ~ 1.5m between. Q: which kinds of air index exceeded, would lead to Alarm sound? A: Just HCHO data more than 0.10mg / m3, would lead to Beep sound. which can be canceled as request . Q : What are the Standard Accessories -Main device -USB Charging cable -User guide
