Rotating-vane thermo-anemometer that reads air velocity in fpm, m/s, km/h, mph, knots, and Beaufort scale while simultaneously calculating air volume in CFM or CMM. A dual LCD shows velocity and temperature together, with Min/Max/Average, data hold, and onboard logging for up to 99 readings. Covers a 0.4-30 m/s velocity range and -20 to 60C temperature range, and ships with a carrying case. This unit includes a NIST-traceable calibration certificate with data and uncertainties.
