BASIC INFO
Testo 425 Hot wire anemometer Order-No: 0560 4251
Product Description
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.
Min/Max/Average values make comparisons fast and easy
Compact thermal sensor is ideal for in-duct readings
Measures air velocity from 0 to 4000 FPM
Bright backlit display provides easy viewing in any environment
Delivery Scope
testo 425 thermal anemometer with permanently attached flow probe including temperature measurement and telescope (max. 820 mm), calibration protocol, and battery
Telescoping hot wire probe
Measures velocity, volume flow (CFM), and temperature
Timed and multi-point average flow calculations
Auto-off function saves battery life
The testo 425 hot wire anemometer can measure cubic feet per minute (CFM) when conducting duct testing, as well as easily switch between flow and temperature readings. The telescoping handle of the thermal probe on this CFM meter makes it easy to reach ductwork above your head.
