The testo 435 multi-function climate measuring instrument is available in four versions. This testo 435-3 version 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 (optional).
Take advantage of further optional probes which you can attach to the testo 435-3 multi-function climate measuring instrument. This means you are ideally equipped when your work involves adjusting ventilation and air conditioning systems or assessing air quality.
