Particle Counter PM2.5 PM10 Formaldehyde HCHO Temp. Humidity Meter Tester 4in1

Description

gm8804
Introduction:
This product is a type of portable multifunctional air quality detector that can simultaneously detect the concentration of airborne particulates,
formaldehyde
concentration, temperature and humidity.
This instrument can achieve accurate measurement, real-time response,
continuous collection and detection of formaldehyde and particulate matter concentration in the air.
Its minimum resolution particle size is 0.3um.
This detector has the following features:
1.
Dynamic and real-time detection of PM2.5, PM10 and formaldehyde concentration in the air.
2.
Environmental temperature and humidity measurement and temperature unit conversion.
3.
Switching between three different display modes.
4.
Display of the maximum and minimum values.
5.
Data hold function.
6.
Sound and light alarm settings.
7.
LCD backlight display of air quality level.
