From the Manufacturer
Heavy Duty CFM Hot Wire Thermo-Anemometer uses a telescoping probe (extends up to 3-Foot) that's 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. A built-in RS-232 interface can be used with optional Data Acquisition software and cable for recording measurements directly to your PC. Comes complete with telescoping probe with 5.5-Foot cable and 4 AA batteries.
