Order-Nr.  0560 6060

  • Precise moisture measurements in wood / cement etc.

  • Characteristic curves for wood / building materials

  • Hold function: freezes the last reading for convenient use

  • Backlit display for use in all lighting conditions

The testo 606-1 moisture meter measures the moisture content of wood, walls, and many other surfaces and materials. Ideal for professionals and private users.

Product Description

The testo 606-1 moisture meter can measure different types of wood and building materials. It is easy to use, and comes with a wide range of quality features.
The two ram electrodes are pushed firmly into the wood or building material, where they measure the moisture content as a percentage based on the dry mass (dry weight).
There is a hold function and a backlit display, for use in all lighting conditions. A protective cap and belt bag ensure that the meter is stored safely, and a hand strap prevents the meter from being dropped.

Practical – the characteristic curves in the testo 606-1 moisture meter

The testo 606-1 comes complete with a wide range of characteristic curves for wood and building materials. This allows the measured moisture content to be shown directly, as a weight percentage.
Characteristic curves for precise wood moisture measurements:
  • beech
  • spruce
  • larch
  • oak
  • pine
  • maple
Characteristic curves for precise building material measurements:
  • cement screed
  • concrete
  • plaster
  • anhydrite screed
  • cement mortar
  • limestone mortar
  • brickwork

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 craftsman, 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 measuring methods also include the option of measuring resistance by means of the electrical conductivity of the material or the magnetic flux leakage method, which measures using the electrical field in the material.

The testo 606-1 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. Characteristic curves are available for measuring wood moisture in beech, fir, larch, oak, pine and maple wood. There are a further five characteristics stored in the instrument.

The measuring instrument uses two electrodes rammed into the material 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.
