Multi-functional
measuring instrument
testo 435
• Large range of probes (optional):
- IAQ probe for evaluating indoor air quality
- Thermal probes with integrated measurement of
temperature and humidity
- Vane and hot wire probes
- Integrated differential pressure probe for Pitot tube
measurement (see variants)
- Radio probe for temperature and humidity (see variants)
• Easy operation
• PC software for analyzing, archiving and documenting the
readings
The multi-functional measuring instrument testo 435 is your
reliable partner for indoor air analysis, and for regulating
VAC systems to optimise energy use. To evaluate indoor air
quality CO
2
, relative humidity and room temperature param-
eters are available.
In addition, the absolute pressure, draught, lux, U-value and
surface temperature can be defined. To determine the volu-
metric flow all the options for flow measurement are avail-
able to you - e.g. thermal probes, vanes and Pitot tubes.
