  1. Multi-function climate measuring instrument: measure up to 6 measurement parameters at the same time
  2. Internal reading memory for up to 3,000 readings
  3. Automatic allocation of the duct cross-section to the measuring location (max. 99 measuring locations)
  4. Automatic mean value calculation and determination of the volume flow
  5. You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.
    Ventilation and air conditioning systems are used more and more frequently to ensure user independent fresh air supply and thermal comfort in buildings. The testo 445 climate measuring instrument helps you check the system is functioning properly and operating efficiently. This is because the measuring instrument can determine all the relevant measurement parameters for you.

    testo 445 climate measuring instrument: an overview of the advantages

    The testo 445 climate measuring instrument has two inputs for connecting external probes (which can be ordered separately). At Testo, you have a large selection of suitable probes for the testo 445 climate measuring instrument. Depending on which probe you decide on, you can determine the following parameters:
    • Air velocity (in ventilation ducts, at duct outlets and on extractors)
    • Volume flow
    • Temperature
    • Relative air humidity
    • Dew point
    • Absolute humidity
    • Degree of humidity
    • Enthalpy
    • Pressure
    • CO in indoor air
    Further practical features of the climate measuring instrument: its internal memory records up to 3,000 readings. The automatic allocation of the duct cross-section is also particularly useful. This means you can save the measurement data so that it is linked to the measuring location (up to 99 measuring locations). The mean value, the last measured value and the min./max. values can be displayed simply by pressing a key.

    As optional accessories for the climate measuring instrument, we recommend you get the testo fast printer to print data out directly at the measuring location and the ComSoft software for convenient data analysis on the PC.
