TES 5322 PM2.5 Air Quality Monitor

TES 5322 PM2.5 Air Quality Monitor


TES 5322 PM2.5 Air Quality Monitor converts the concentration of PM2.5 and VOCs in the air into visual data, and evaluate the air quality comprehensively. 

Visual and audio alarm will be actived when the air quality reached a critical or alarm limit values.

Particle pollution comes from many different type of sources. 

Fine particle (2.5 micrometers in diameter and smaller) include power plants, industrial processes, vehicle tailpipes, wood stoves, and wildfires. 

Coarse particles (between 2.5 and 10 micrometers) come from crushing and grinding operations, road dust, and some agricultural operations. 


  • Fine particulate matter (PM2.5) measurement.
  • Mix gases (VOCs-Volatile organic compounds) measurement.High sensitivity to H2, C2H5OH, C4H10, CO and CH4.
  • Monitoring air pollutant source from dust, petrochemical industry, steel-making plant, thermal power plant, restaurant, smoke, burning plants, driving automobiles.
  • The meter is a real-time air quality monitor instrument used to monitor the concentration of PM2.5, humidity and temperature in the indoor environment.
  • VOCs time weighted average reading.
