Testo 435 IAQ/VAC Measuring Instrument


The Testo 435 provides the possibility of analysing indoor air. On the one hand, this serves as an indicator of the well-being of the people at their workplace, and on the other hand as an important and deciding factor in storage and production processes.

In addition to this, the indoor air quality indicates whether the air conditioning system is working with optimal energy-efficiency, or whether it needs to be adjusted with the help of Testo 435.

The parameters CO2, relative humidity and room air temperature are available for evaluating indoor air quality. Additionally, absolute pressure, draughts, lux and surface temperature can be determined.

To determine volume flow, all the possibilities of flow measurement are available, such as thermal probes, vane probes and Pitot tubes.

  Instrument memory for 10,000 readings
  PC software for analysis, filing and documentation of measurement data
  IAQ probe, lux probe and comfort level probe
  Thermal probes, vane measurement and built-in differential pressure probe probe for Pitot tube measurement
  Radio probe for temperature and humidity
  Protection class IP54

The right probe for every application

The parameters CO2, relative humidity and room air temperature are available for evaluating indoor air quality. Additionally, absolute pressure, draughts, lux and surface temperature can be determined.

The new probe for Indoor Air Quality (IAQ) measures the parameters CO2, relative humidity and room air temperature in order to evaluate room air quality. Absolute pressure is also available.

People react sensitively to draughts. An objective evaluation of the room air velocity present in the room is made using the degree of turbulence probe.

Bad light conditions affect the quality of work. The new lux probe reliably records the light conditions at the workplace.

The cross-band probe is outstanding for surface measurements. The cross-band assumes the actual temperature of the object to be measured in a few seconds.

Temperature and humidity measurement have been integrated in the new thermal probe, for measurements in ducts. Flow speed, volume flow, air humidity and air temperature can thus be measured in one measurement sequence.



The vane probe with a diameter of 60 mm is suited to integrated measurements, e.g. at outlets. For duct measurements, a 16 mm vane probe with a broad measurement range from 0.6...40 m/s is available. The Pitot tube measurement is ideal for high air velocities and with contaminated air. A 25 hPa differential pressure probe is integrated into 435-3 and 435- 4 for this purpose.
