VELOCITY MULTIFUNCTION METER
Testo 435-3 Velocity Multifunction Meter

435-3 Velocity Multifunction Meter.
testo 435-3, multi-functional measuring instrument with built-in differential pressure measurement for air conditioning, ventilation and Indoor Air Quality, with battery and calibration protocol.
The ambient air conditions measuring instrument for your introduction to professional ambient air measurement engineering. It has the right measurement engineering, e.g. thermal probes, vane or Pitot tube measurement, for every application and flow speed.

 

  • IAQ probe for assessing Indoor Air Quality

  • Thermal probes, vane measurement and
    built-in differential pressure probe for
    Pitot tube measurement

  • Radio probe for temperature

  • Testo printer for documentation purposes

  • Protection class IP54

The new IAQ probe measures Indoor Air Quality by measuring the CO2 level, air moisture and air temperature. Temperature and humidity measurement is built-in in the new thermal probe.
In addition, it is also possible to connect additional temperature probes to, for example, accurately measure surface temperature. Readings from up to 3 temperature probes can be displayed in the clearly laid-out measuring instrument display; data transmission is by radio, i.e. wireless.
Measurement data is printed on site on the Testo printer.
