Thermo hygrometer 608-1 for continuous measurement of moisture, temperature and dew point. With a large clear display, it can either be placed on the table or hung on the wall. The patented Testo moisture sensor is stable over long periods, robust and resistant to condensation.

Model 608-2: Same as 608-1, but with greater accuracy, greater measuring range, and equipped with an alarm function that sounds when limits are exceeded or undershot.

External sensors cannot be connected. Battery not included.
