Digital hot wire anemometer
Part number 0563 0425
Includes cable connected, telescopic hot wire probe (maximum length 32”)
Simple, fast and precise flow measurement and volume flow calculation in the ventilation duct
Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App
Testo 425 - Hot-Wire Anemometer Telescoping handle extends to 33 inches Measures velocity, volume flow (CFM), and temperature Compact thermal sensor is ideal for in-duct readings Measures air velocity from 0 to 4000 FPMThe testo 425 is a compact anemometer with a fixed thermal flow velocity probe. The probe head has a diameter of 7.5 mm. With the extendable telescope (length max. 820 mm), the measuring instrument is suitable for flow velocity measurement in ducts.The testo 425 also measures extremely accurately in the low flow velocity range. The volume flow is directly shown in the display. For the purposes of volume flow calculation, the duct area can be easily entered into the testo 425. In addition to this, the instrument can be switched over to display the current temperature. Timed and point mean value calculation provide information on the average volume flow, flow velocity and temperature measurement value. The Hold function allows the current measurement value to be frozen in the display, min./max. values are also displayed at the press of a button.
