The testo 425 hot wire anemometer provides incredible accuracy and is easy to use. The telescoping handle of this CFM meter extends to 33 inches, putting even high-up ductwork within reach. The testo 425 anemometer is ideally suited for low flow and velocity applications, and provides accurate, fast, and easy readings.

Features:

Telescoping hot wire probe
Measures velocity, volume flow (CFM), and temperature
Timed and multi-point average flow calculations
Auto-off function saves battery life
