EXTECH 407119 Heavy Duty Anemometer

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 as an instantaneous value or up to 20 point average
Record/Recall MIN and MAX readings
Super large 1.4" (99,999 count) 5 Digit LCD display
Data Hold plus Auto Power Off
Built-in RS-232 PC interface with optional Data Acquisition software and cable

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.

Includes:
AA Batteries
Telescoping probe with 5.5' Cable
