testo 445 Multifunctional measuring instrument including battery and factory report.
Product Introduction:
testo 445 Multifunctional measuring instrument can measure temperature, relative humidity, dew point, absolute humidity, humidity, enthalpy and various wind speeds (in pipe, pipe outlet or radiator), air volume, pressure and indoor air quality
The measurement data and its measurement address can be stored in the instrument and analyzed by PC or printed on site by testo printer
Advantages at a glance:
Automatic mean calculation and air volume measurement
Automatically records the cross-sectional area of different addresses (up to 99 addresses)
Built-in data storage (3,000 readings)
6 parameters can be measured simultaneously
