Text 425Thermal anemometer, fixed connection wind speed probe, with telescopic handle (longest)820mm）Can simultaneously measure temperature; Including batteries and calibration certificates.

Text 425Precision anemometer, fixedly connected to thermal sensitive wind speed probe,Equipped with a telescopic handle.testo 425It can directly display the air volume value. As long as the cross-sectional area of the pipeline is input, the instrument can accurately calculate the air volume. In addition, it can be freely switched to the current temperature reading. The instrument comes with a time period/The multi-point average calculation function can calculate the average values of air volume, wind speed, and temperature. At the same time, it can display the maximum and minimum values, Using the hold key can keep the current reading.

? Advantages Overview：

·Measure temperature, wind speed, and air volume

·Calculate multiple points/Time period average

·Display maximum value/minimum

·Hold key, used to maintain reading

·Display screen with backlight

·Auto Power Off
