Overview

The Testo 435-3 version of Testo 435 multi-function climate measuring instrument has an integrated differential pressure sensor with a 0-25 hPa measuring range. Differential pressure measurement enables you to check filters in ventilation and air conditioning systems or to measure air velocity with a Pitot tube.
Hence Testo 435-3 multi-function climate measuring instrument with its optional probes ideally equips you for adjusting ventilation and air conditioning systems or assessing air quality.
It has attachable probes (optional) for assessing air quality, IAQ probe (Indoor Air Quality) for assessing air quality – measures CO2, air temperature, air humidity and absolute pressure.
