435-3 Air Velocity Multifunction Meter.
435-3 Air Velocity Multifunction Meter.
Model 435-3,
multi-functional measuring instrument with built-in differential pressure measurement for air
conditioning,
ventilation and Indoor Air Quality, with battery and calibration protocol.
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.

Model | Description |
---|---|
0560 4351 | 435-1 Multifunction Meter |
0563 4352 | 435-2 Multifunction Meter w/memory & software |
0560 4353 | 435-3 Multifunction Meter with integral diff pressure |
0563 4354 | 435-4 Multifunction Meter w/memory, software & diff. press. |
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.
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.
