The Testo 605-H1 compact thermohygrometer enables reliable measurement of humidity and air temperature and calculation of the dew point. It has a permanently mounted probe shaft which means it is excellent when it comes to carrying out check measurements in ventilation ducts.

If you are looking for a compact, user-friendly thermohygrometer, 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 °C td range. The built-in Testo humidity sensor ensures reliable measurement results with long-term stability.

The thermohygrometer 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 thermohygrometer while doing so.

The design of the Testo 605-H1 temperature and humidity measuring instrument has been well thought through, right down to the details: the display can be pivoted into different positions, enabling the measuring values to be read off easily.
