Air Quality


Multifunction PM2.5 Indoor Air Quality Monitor

eYc TGP03, PM2.5 multifunction 4-in-1 air quality monitor, which is specially used to monitor 4 kinds of physical quantities as PM2.5, CO2 (carbon dioxide), temperature and humidity.
There are 3 types of excellent sensors in this monitor such as MEMS, NDIR, and Infrared LED.
That is why we have the nicer Long-term stability of measuring and react quickly.
TGP03 is easy to install and featured with compact size and elegant outlook, and also provide programmable software to monitor and record the data via RS-485.

Stealthy Fatal Killer PM2.5 exist in the ambient. It threatens human health  if the value of PM2.5 and CO2 excess the standard 35μg/m3 and 700 PPM.
