MULTIFUNCTION MEASUREMENT
  
Testo 445 Multifunction Measurement

445 Multifunction Instrument Measurement Temperature, Humidity, Dew Point, Air Velocity, Pressure
The Testo 445 VAC measuring instrument with its multi-function technology measures temperature, relative humidity, dew point, absolute humidity, degree of humidity, enthalpy, all types of air velocity
(in ducts, duct openings or in extractors), pressure and indoor air quality.
The Testo 445 VAC measuring instrument with its multi-function technology measures all types of air velocity in addition to temperature, relative humidity, dew point, absolute humidity degree of humidity, enthalpy.

 

  • Automatic mean calculation and
    volume flow measurement

  • Automatic allocation of duct
    cross-section to location

  • Internal data memory

  • Quick Printing of data on location

  • TopSafe for industrial applications

 

Logged data can be uploaded to a PC.

The instrument for daily measuring tasks in the VAC branch.

  • Standard velocity measurements via
    averaging

  • Volume flow measurements in duct
    outlets

  • Comparison of relative humidity in the
    air sucked in from outdoors with the
    conditioned air flowing out from the
    exhaust outlets

  • Monitors filters by measuring differential
    pressure

  • Monitors indoor air quality with CO2 probe
Data can be displayed, saved and exported.
