– You have the option of connecting thermal anemometers and vane anemometers for measuring air velocity and volumetric flow in ventilation ducts
– Air quality: measurement of CO2, air humidity, air temperature and absolute pressure with the optional IAQ probe
– Display of dew point distance, min., max. and mean values
– Illuminated display
testo 435 is a series of multi-function climate measuring instruments made by Testo. The testo 435-1 version is the entry-level measuring instrument in this series. You can use this to carry out measurements which you need to adjust ventilation and air conditioning systems and assess air quality. For this we offer you a comprehensive range of optional probes and sensors to choose from.
