Testo 435-3 Offers

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. 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.

Features

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
Protection class IP54
