Handheld anemometer is accurate, economical

Priced under $500, the HHF42 portable hot-wire anemometer provides readings from 40 to 3,940 ft/min with resolution of 1 ft/min, or readings in m/s, km/h, knots, or miles/h. It also measures temperature from 0°C/32°F to 50°C/122°F, and displays temperature and air velocity together on its 3½-digit 13-mm LCD.

Accuracy for velocity readings is ± (5% reading +1 d) or ±(1% Full Scale +1 d), whichever is greater, and for temperature, 0.8°C/1.5°F. The meter can record min and max reading with recall and comes with a carrying case and a slim probe. An NIST-traceable calibration certificate is optionally available. (From $419 — available now.)
