Mini Thermo-Anemometer with Humidity

The Air Flow Meter 45158 is a waterproof, pocket-sized thermo-anemometer that measures air velocity, temperature, and wind chill. On the LCD panel, air velocity, temperature, and wind chill are all displayed simultaneously. It has adjustable average intervals of 5, 10, or 13 seconds, as well as data hold and auto power off options. The foldable, protected casing extends to 229 mm (9 in) for increased reach. The 45158 is tripod mountable and has a battery and 109.2 cm (43 in) lanyard.
