Product Description

Testo 616, the compact sized instrument for moisture measurement aids in precise and non-destructive measurement of moisture content of wood and building materials and of monitoring the drying process after water damage. Inspect the moisture content as a weight percentage compared to the dry weight by simply selecting the characteristic curve and placing the meter’s measuring claw against the surface of the material. You can also save the reading to your meter by just pressing the relevant key.

Although the measuring claw only comes into contact with the surface, wall or flooring that is being measured, it is able to determine the moisture content of the wood or other material down to a depth of 5 cm.

Ideal areas of use for the testo 616 moisture meter

The testo 616 moisture meter is a professional measuring device that can be used in areas as diverse as water damage restoration or carpentry or joinery.

–  Moisture damage detection: the non-destructive method for finding moisture in walls and floors

–  Monitoring drying processes: from carrying out moisture inspections to meeting building schedules to controlled drying after water damage – the non-destructive method for determining the moisture content in wood and building materials

–  Moisture in wood: for checking the moisture content of wood that has been stored prior to processing

Determining moisture in wood

Moisture content is a decisive factor in the further processing and use of 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.
The testo 616 enables the quick and non-destructive examination of the material moisture characteristics in timber. Characteristic curves are available for measuring wood moisture in soft and hard woods, and chipboard. These characteristic curves were developed in cooperation with the LPI institute.

Monitoring drying processes

Whether freshly laid screed, or monitored drying of moisture damage, timely determination of the required moisture level will save time and therefore money.

Screeds are laid in the in interior works stage, generally after plastering. The flooring and painting and decorating then follow. The drying behaviour is therefore a significant factor in the works schedule, primarily because the laying of flooring depends on this.

The moisture measurement establishes readiness for flooring; liability for the flooring is thus transferred to the respective trade installing the flooring. An important part of this work is therefore documentation and assurance in the testing for readiness for flooring.

What is the extent of moisture damage? This question has to be answered in order to decide which instruments are to be used to speed up the drying process.

The testo 616 can be used to quickly and non-destructively examine the material moisture in building materials. It also makes work easier when drying processes for floors, walls and surfaces have to be observed.

Diagnosing building moisture

Moisture may penetrate walls, floors and ceilings due to pipes bursting or water ingress. Some of this moisture damage may not be detected immediately. Rising or ingressing water, faulty rain and waste water drains, or even blocked drains and inadequate seepage capacity may be the cause.

Depending on where it is getting out or in, the moisture can spread in different ways; enormous damage may be done if discovered too late. Therefore, measurement of the material moisture in the affected places is necessary to be able to identify the source of the damage.

The testo 616 can be used to quickly and non-destructively examine the material moisture in building materials. The measuring clamp is laid on the surface; the value can be read immediately. The measurement results are calculated up to a depth of 5 cm and can be recorded at the touch of a button. The readings are displayed in percent by weight in comparison to the dry mass of the material.

For easy, quick handling, characteristics are already stored in testo 616 for the following construction materials: anhydrite screed, cement screed, lime sand brick, aerated concrete, concrete, vertically perforated brick and solid brick; these aid detection of wet places in the construction materials.
