TESTO-425 thermal anemometer Introduction
TESTO-425 precision anemometer with fixed connection thermal speed probe with telescopic handle. TESTO-425 can directly display the air volume value. As long as the cross-sectional area of the pipe is input, the instrument can accurately calculate the air volume. In addition, you can switch to the current temperature readings at will. The instrument has a time period/multipoint average calculation function that calculates the average of air volume, wind speed and temperature. At the same time, the maximum and minimum values can be displayed, and the current reading can be maintained using the hold button. Features
1.Measure temperature, wind speed and air volume
