EXTECH 407119 Heavy Duty CFM Hot Wire Anemometer
Specification
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
