Indoor air quality
Features of IAQ Air Quality Monitor
• Stable NDIR sensor to monitor CO2
• Calculates % outside air from CO2 or temperature
• Displays humidity as %RH, dew point, and wet    bulb
• Manual or continuous data logging
• Stores 12,700+ sets of downloadable readings
   with time and date stamp
• Includes LogDat2™ software and interface cable    to download to a PC
• Statistics function for average, maximum, and    minimum values
• Displays three parameters simultaneously
• Real-time CO2 readings 0 to 5,000 parts per    million (PPM)
• Integrated NDIR sensor
Carbon Monoxide, carbon dioxide air quality monitor
The IAQ 930 Series continuously monitors carbon dioxide and carbon monoxide concentration, temperature and relative humidity. The four air quality parameters are displayed simultaneously on the LCD display. The built in data logging kit can store up to 26,900 data points with 4 parameters enabled and the software facilitates the download and manipulation of the data on a Windows PC. 

These Indoor Air Quality Meters are the ideal tools for investigating indoor air quality and performing thermal comfort studies. They simultaneously measure and data log multiple parameters. The CF920 quickly and accurately measures carbon dioxide (CO2),
temperature, humidity, and calculates dew point, wet bulb temperature,
and % outside air. The Model CF930 adds a measurement of carbon monoxide (CO).


<<Model CF910 CO2 Meter>>

The CF910 CO2 Meter is an excellent handheld diagnostic instrument for measuring and monitoring carbon dioxide levels. HVAC professionals use it for conducting IAQ surveys, checking air changes, and evaluating ventilation systems in schools, offices, factories and hospitals.

Features and Benefits
• Statistics function for average, maximum,
and minimum values
• Large display
• Real-time CO2 readings in parts per million (PPM)
from (0–5,000ppm)
• Integrated NDIR sensor
