Reed Instruments SD-4207-NIST Thermo-Anemometer/Data Logger with NIST Traceable Certificate, Air Velocity Range: 0.4 to 30.0 m/s

The REED Thermo-Anemometer Data Logger measures air velocity as well as temperature with a type J/type K thermocouple thermometer. The low frication ball-bearing, rotating vane probe ensures high accuracy readings. The meter has a thermistor temperature sensor for a fast response time and air velocity is measured in m/s, fpm, km/h, mph or knots. It features automatic temperature compensation, an easy to read LCD with backlight, data hold and max/min record and a real time data logger with integral 2GB SD memory card (optional). Just plug the SD card into the computer and it downloads directly to EXCEL.
