EXTECH 407119 Heavy Duty CFM Hot Wire Anemometer

The 407119 utilizes a telescoping antenna with built-in air velocity and temperature measurement transducers. CFM ( cubic feet per minute) measurements are displayed after manually entering the area of the duct and then taking an air velocity measurement. The 407119 includes a MIN/ MAX display and a 20-point averaging feature. Careful use of this meter will provide years of reliable service. Features: Air velocity measurements as low as 40ft/ min Telescoping probe is ideal for use in ducts and ventilating systems; extends up to 4ft ( 1.22m) long 20 point averaging for airflow Record and recall MIN/ MAX readings Data Hold plus Auto power off Built-in RS-232 PC Interface Includes: ( 4) AA Batteries ( 1) Telescoping probe with 5.5' Cable Specifications: General Specifications Display : Dual function 4-digit LCD Measurement units : Air Velocity - m/ s, km/ h, ft/ min, knots, mph; Air Flow - CMM ( m³ / min) and CFM ( ft³ / min) ; Temp - ° C and ° F Data hold : Freezes displayed reading Sampling rate : 1 second approx.
