Testo 425 Product Sheet

The compact testo 425 is an easy to use anemometer with attached thermal probe on a telescopic handle. Just enter the duct measurements directly into the testo 425 and volume flow measurements (cfm) are shown on the clear display. You can switch between flow and temperature readings easily. Timed and multi-point mean flow calculations allow easy flow analysis, volume accumulation estimates, and temperature variation monitoring. Min-Max values are one button simple, while the "Hold" function freezes the current readings in the display for easy data recording.
