The TSI Alnor CF920 and CF930 CompuFlow CO2 meters are the ideal tools for investigating indoor air quality and performing thermal comfort studies. The CF920 and CF930 quickly and accurately measures and data logs multiple parameters including carbon dioxide, temperature and humidity while simultaneously calculating dew point, wet bulb temperature, and % outside air. The CF930 model also measures carbon monoxide.

Features of the TSI Alnor CF920 and CF930 CompuFlow CO2 meters include a stable NDIR sensor to monitor CO2, manual or continuous data logging, and storage of 12,700+ sets of downloadable readings with time and date stamp. The CF920 and CF930 also display three parameters simultaneously and have a statistics function for average, maximum and minimum values.

The TSI Alnor CF920 and CF930 CompuFlow CO2 meters ship complete with hard carrying case, four AA alkaline batteries, calibration collar, operation and service manual and NIST calibration certificate, LogDat2 downloading software and computer cable.
