Extech SD dataloggers accurately monitor and record several combinations of key environmental factors including temperature, humidity, carbon dioxide, and barometric pressure levels.

Extech's SD dataloggers record directly to a Microsoft Excel® file, eliminating file conversions or imports. Large multiple-reading displays indicate real-time measurements while data are saved to a 2GB SD card (included) for easy transfer to a laptop or PC. Sampling rates range from once every 5 seconds to every 10 minutes.
