The Extech 45158 is a waterproof, pocket sized Thermo-Anemometer for air velocity, temperature, and wind chill measurements. Simultaneously display air velocity and temperature or wind chill on the LCD screen. It features selectable averaging functions of 5, 10, or 13 second intervals, as well as data hold and auto power off functions. The fold up, protective housing extends to 229 mm (9 in) for a better reach. The 45158 is tripod mountable and comes with a battery and 109.2 cm (43 in) lanyard.
