This meter measures CO2 level, Air Temperature, Dew Point (DP), 
Wet Bulb Temperature (WB) and Humidity (RH) and is an ideal instrument for Indoor Air Quality (IAQ) diagnosis. 

Industrial, commercial and residential application 

Features:

1.Triple displays of CO2 level, temperature (°C/°F) and Humidity
2.Stable NDIR sensor for CO2 detection

• Statistics of weighted averages
• TWA (8 hours weighted average)
• STEL (15 minutes-weighted average)

3.Updates reading every second on the meter, output to PC every 2 seconds
