The Testo 435 is a new ambient air conditions measuring instrument for asssessing Indoor Air Quality and tuning and testing HVAC systems. It stands out on account of its efficient measurement process. The user-friendly measuring instrument has the right measurement engineering for every application and different flow speeds; for example, thermal probes, vane or Pitot tube measurement.

Probe-controlled menus and selectable user profiles, e.g. for duct measurement or long-term measurement, ensure the user-friendliest operation possible. The new IAQ probe measures Indoor Air Quality by measuring the CO2 level, air moisture and air temperature. In addition, lux and comfort level probes can be connected to measure draft air. Clear analysis and archiving ensure convenient documentation. Temperature and humidity measurement is built-in in the new thermal probe. The special flow protocol professionally documents duct measurements and it is also possible to connect additional temperature and humidity probes. Readings from up to 3 temperature or humidity probes can be displayed in the measuring instrument; data transmission is wireless.
