REED R4000SD Data Logging Vane Thermo-Anemometer
The R4000SD features a built-in contact thermometer that monitors air velocity and temperature. It has automatic temperature compensation, Data hold, Max/Min functions, and a backlit LCD display that is easy to read. A user can manually record up to 99 readings using an SD card (max 16GB) or automatically by setting a preferred sample rate from 1 to 3600 seconds. Without using any software, quickly create an Excel file with raw data. A tripod and AC adaptor are available as optional extras for long-term monitoring. Air velocity (fpm, m/s, kph, mph, and knots) and temperature are measured. Type J/K thermocouple choice for contact temperature measuring. For quick air temperature readings, use a thermistor sensor. A revolving vane probe with low friction ball bearings ensures high accuracy readings.
