The testo 605-H1 air moisture meter allows you to measure relative humidity and ambient temperature, as well as calculate the dew point.This device has a built-in humidity sensor so you can easily take measurements in air ducts.

The Testo 605-H1 thermohygrometer is a compact and easy-to-use laboratory recorder. The Testo 605-H1 can measure relative humidity and ambient temperature and calculates the dew point from -20 to +50 °C td . Testo's built-in humidity sensor provides stable readings.
The thermohygrometer is great for measurements during production, storage of goods, in offices and server rooms.
The testo 605-H1 meter is particularly useful for measurements in ventilation ducts. Thanks to the rotating display head , measurement results are always easy to read.

In addition, the humidity sensor, located at the end of the probe, is protected from mechanical injury.

The kit includes testo 605-H1 thermohygrometer with dew point calculation, clamp, handle, batteries.
