Relative Humidity - Temperature - Carbon Dioxide Datalogging Kit

Record and log relative humidity, temperature & CO₂ data…and graph right on your PC!

Features & Applications:

Poor Air quality cannot only affect ambient Air, but result in decay or damage to a structure. Equipped with infrared technology to accurately measure these components. Measure RH, temperature and CO₂ with precision-enabling you to assess The conditions in The test area.

Designed for residential and commercial applications, it also has The ability to calculate and display cfm/person ventilation rate-hence identifying ventilation-related problems such as moisture build-up, combustion gas build-up, etc. Record your findings on your computer utilizing The included graphical software and cable.
