Features Air velocity measurements as low as 40ft/min Telescoping probe is ideal for use in ducts and ventilating systems; extends up to 3ft (940mm) long Measures air volume in CFM (ft3/min) and CMM (m3/min) plus Temperature simultaneously Air Flow displayed in 2 modes: Instantaneous value or up to 20 point average Record/Recall MIN and MAX readings Large 1.4" (99,999 count) LCD display Data Hold plus Auto Power Off Specifications Air Velocity ft/min: 40 to 3346ft/min MPH: 0.5 to 38.0MPH knots: 0.4 to 33.0knots m/s: 0.2 to 17.0m/s km/h: 0.7 to 61.2km/h Temperature °F: 32 to 122°F °C: 0 to 50°C Airflow CMM (m³/min): 0 to 36,000m³/min CFM (ft³/min): 0 to 1,271,200ft³/min 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.
