Accurately measure Air Flow (CFM/CMM) or Air velocity plus °F/°C Temperature

The 407119 Heavy Duty CFM Hot Wire Thermo--Anemometer uses a telescoping probe (extends up to 3 ft) which is ideal for use in ducts and ventilating systems. It can accurately measure Air Flow (CFM/CMM), Air Velocity and Temperature. Air Flow can be displayed as an instantaneous value or up to a 20 point average. Additional functions include Data Hold, Min/Max, and Auto power off. Comes complete with telescoping probe with 5.5ft cable, and 4 x AA batteries.
