REED R4000SD-NIST Data Logging Vane Thermo-Anemometer - R4000SD-NIST

The Reed R4000SD measures air velocity, air temperature and has a built-in contact thermometer. Featuring automatic temperature compensation, Data hold, Max/Min functions, and an easy-to-read backlit LCD display. Using a SD card (max 16GB), a user can manually record up to 99 readings or automatically by selecting a desired sampling rate from 1 to 3600 seconds. Quickly generate an Excel file with raw data, all without the use of software. Optional accessories include a tripod and AC adapter for continuous long-term monitoring.
