T660 material moisture measuring device

Professional hand-held measuring device for the quick, non-destructive determination of moisture distributions in near-surface areas


The T660 is ideally suited for the quick, non-destructive determination of moisture distribution in near-surface areas to about 4 cm.

Based on the T660's integrated material pre-selection function for anhydrite and cementitious screed the measurement results (indicative) can on demand be shown directly in mass % or CM % on the colour display of the T660.

The integrated conversion of measured values is a practical tool, in particular for floor layers to quickly check the readiness for covering.

In addition to the preliminary check of the building materials' readiness for covering for CM measurements the T660 is also suited for non-destructive wood moisture measurements according to the dielectric measurement method (indicative).

Brilliant large-digit display

The T660 comes equipped with particular display glass ensuring high-contrast presentation even in bright sunlight as well as enabling the quick and reliable detection of the moisture distribution in wall or floor areas when combined with the large-digit, real-time measurement value display.

Integrated alarm function

Handy and time-saving: Prior to measuring you can define an individual limit value in the T660's settings. Should this alarm limit value be exceeded in the course of measuring, an acoustic warning signal is emitted automatically.

This way, large wall and floor areas can be measured quickly and effectively. During measuring, you can focus exclusively on the measuring object without the need to permanently keep an eye on the displayed measuring results.

Also ideally suited for combined building diagnostics measurements using the material moisture measuring device T610

Owing to the combined measurement of near-surface moisture with the T660 and of sub-surface moisture with the T610, complex correlations can be distinguished, narrowed down and classified, e.g. hygroscopic humidity occurrences resulting from salinization or leak detection. In the course of this the T660 captures the topmost two to four cm of the construction material and the T610 measures the volume moisture values to a depth of 30 cm.

Significant results regarding a multi-dimensional moisture distribution can be obtained via grid measurement based on surface and sub-surface moisture measurement values. With an active USB connection to the measuring device the MultiMeasure Studio software included in the scope of delivery provides a convenient assistance function for the creation and visualization of grid measurements.

Finally one software for basically all measuring devices

As optionally available Professional version MultiMeasure Studio offers yet more possibilities and is not only perfectly suitable for fully compatible devices like the T660.

Owners of partially compatible or isolated measuring instruments can also benefit from this software, since it enables the analysis and administration of all measuring projects and customer data across multiple devices in a single application!

Using the unique report generating function you can create professional measurement reports in a trice:

Numerous boilerplate texts for building diagnostics, moisture measurement, leak detection and thermography are already included completely formulated (German version only).
