Testo 606-2 - Moisture meter for material moisture and relative humidity

Special Price 14301

Regular Price: 15731.00


The testo 606-2 moisture meter for material moisture with relative humidity and air temperature measurement allows you to measure the moisture content in wood and building materials – and the surrounding environment too. This means that you can now also check the storage and drying conditions quickly and easily.

  • Precise moisture measurements in wood and building materials
  • Ideal for carrying out relative humidity and air temperature measurements to check storage and drying
  • Identifying and preventing problems using dew point and wet bulb calculations
  • Easy to use; backlit display for use in all lighting conditionsEasy to use; backlit display for use in all lighting conditions

Product Description

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.

Determining moisture in wood

Moisture content is a decisive factor in the further processing and use of stored timber products. If wood is installed with the wrong moisture content this may result in mechanical deformations (contracting and swelling) at the site where the material is subsequently used, and therefore damage to pieces of furniture or entire supporting structures in buildings. Therefore, before being made into furniture or supporting material by a joiner/carpenter, the suitability of the wood has to be assessed by measuring the moisture content.

Checking the moisture content of fuels, e.g. wood or pellets, is part of the daily duties performed by flue gas inspectors/chimney sweeps. A high moisture content in the fuel means energy loss and a waste of resources.

All Testo wood and building moisture measuring instruments measure the moisture in percentage weight compared to the dry mass (dry weight) of the material.

The testo 606-2 is a particularly practical and easy to use material moisture measuring instrument in pocket size. The material moisture is displayed directly in percentage weight by means of stored material characteristic curves for wood and building materials. Characteristic curves are available for measuring wood moisture in beech, fir, larch, oak, pine and maple wood.

The building moisture measuring instrument uses two electrodes rammed into the wood for its reading. In addition to material moisture, the testo 606-2 also measures humidity and air temperature. In this way, drying conditions, for example, can be assessed on site quickly and reliably.
