“Garden centers, offices, storerooms, laboratories, living quarters: the testo 608-H2 thermo hygrometer’s compact, unobtrusive design allows it to provide constant, up-to-the-minute readings of the indoor temperature and humidity without worrying how to place it, thanks to its wall and table mount for providing greater control and more flexibility.
The testo 608-H2: the practical thermo hygrometer from Testo
The testo 608-H2 thermo hygrometer is the premium choice for all those who do not wish to document and archive measuring data, but who wish to be able to measure and see the temperature and humidity and calculate and display the dewpoint whenever it is needed. The meter comes with a large, easy-to-read display that also allows you to see the readings from a distance.

In addition, the testo 608-H2 can display both minimum and maximum values and has an LED visual alarm that is activated when a threshold has been exceeded. Both the upper and the lower threshold can be individually configured.

The high-precision, long-term stable humidity sensor ensures that your easy-to-use, easy-to-clean measuring device provides you with reliable readings for years to come.

The testo 608-H2 thermo hygrometer has a battery life of approximately one year and a battery status indicator that shows you when the battery is running low.”
