Moisture meter for material moisture and relative humidity – testo 606-2


The testo 606-2 moister meter equips you for moisture measurement in different types of wood and building materials. Apart from measuring moisture in the same way as the testo 606-1 moisture meter, the testo 606-2 also measures the relative humidity and air temperature and calculate the dew point and wet bulb temperature. This means that you can now also measure the relative humidity in the surrounding storage area in addition to the moisture content of the wood you have stored. Armed with such valuable information, you can now easily determine whether the storage conditions are ideal or need to be adjusted.
Characteristic curves for precise moisture measurements in wood and building materials The moisture meter testo 606-2 measures the moisture content of wood and building materials via the two sensing electrodes which are pushed firmly into the material. The characteristic curves of the different materials allow the moisture content to be displayed directly as a weight percentage based on the dry mass (dry weight). The following characteristic curves are stored in the testo 606-2 moisture meter: – For precise moisture measurements in beech, spruce, larch, oak, pine, maple – For detecting moisture and wet places in building materials like cement screed, concrete, plaster, anhydrite screed, cement mortar, lime mortar and bricks.
The testo 606-2 moisture meter – compact, practical, professional, easy to use A variety of practical functions and features including a hold function which freezes the last reading; a backlit display for use in all lighting conditions; a slip-on protective cap, a belt holder which ensures safe storage and a hand strap that helps prevent your meter from being accidentally dropped, makes moisture meter testo 606-2 an efficient instrument for carrying out professional and reliable measurements.
