Five available air velocity units are ft./min (fpm), m/sec, mph, mph and knots; low-friction ball vane wheels provide high accuracy at all air speeds
Small and light enough for one-handed operation; features minimum/maximum store and recall plus data hold and auto power off
Measurement ranges are 1.4 to 108 mph, 0.4 to 30m/sec, 80 to 5810 fpm, 0.9 to 67 mph, 0.8 to 58.3 knots
Measurement accuracy is +/-3% of full-scale value below 20m/sec; +/-4% of full-scale value above 20m/sec
وصف
Air flow displayed in 5 measuring units (ft./min., m/s, km/h, MPH, knots). Min./max. button with recall feature. Data hold freezes current value. Lightweight, easy to hold shape. Low friction ball vane wheel provides high accuracy at all air velocities. A
