If you are looking for a compact, user-friendly thermo hygrometer, the testo 605-H1 is the ideal choice. It measures relative humidity and air temperature and also calculates the dew point in the -20 to +50 degree C td range. The built-in Testo humidity sensor ensures reliable measurement results with long-term stability.
The thermo hygrometer is suitable for check measurements in production, storage, office and server areas. The testo 605-H1 is particularly practical for measurements in ventilation ducts, because it has a permanently mounted probe shaft (length: 125 mm). The bracket which is also supplied enables you to position and fix the probe shaft in the desired location in the ventilation duct. This means you can carry out your measurements without having to hold the thermo hygrometer while doing so.
