Infrared thermohygrometer T260

Precision climate measuring device with outstanding measurement accuracy, integrated pyrometer and dew point alarm function


Whether measuring air and dew point temperature or determining the relative, absolute and specific humidity – the T260 offers all advantages and measurement options of the T210, yet enhances its thermohygrometer function by an integrated laser pyrometer incl. dew point alarm signal generator – all in only one device.

Thus, you can not only flexibly apply the T260 for surface temperature measurements with marking of the measuring site, but thanks to the dew point alarm function it is also possible to quickly and easily locate potential drops below dew point on material surfaces and and positions where mould can form or insulation is poor.

Handy: The integrated dew point alarm function of the T260

During IR measurement the T260 simultaneously indicates the surface temperature of the measuring object and the dew point temperature within the measurement environment.

As soon as the surface temperature falls below the dew point temperature, the T260 notifies you by means of a visual signal and an additional acoustic alarm. The alarm thresholds can be configured individually.

Owing to the alarm function, wall areas can be examined in next to no time and weak points can quickly be detected, for using the T260 you can measure all required measured variables – room temperature, humidity, surface temperature, dew point – with only one measuring device!

Saving, analysing and evaluating measured values

With an active USB connection to the measuring device the MultiMeasure Studio software included in the scope of delivery also allows for online logging of measured values incl. analysis function.

Finally one software for basically all measuring devices

As optionally available Professional version MultiMeasure Studio is not only perfectly suitable for fully compatible devices like the T260.

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).

MultiMeasure Studio software


Climate measurement

The T260 measures the air temperature and the relative humidity. As an alternative, the dew point, absolute humidity in g/m³ or the mass ratio in g/kg is displayed.

The dew point alarm is triggered because the wall surface temperature with 14.1 °C is below the dew point of 15.3 °C.

Dew point alarm

By means of the integrated infrared sensor, the surface temperature of the wall is measured and compared with the dew point temperature. Now just direct the infrared sensor to the wall surface. In this way you can even scan larger surfaces effectively.

If the surface temperature of the wall is near or even below the dew point, an alarm signal is emitted. Additionally, the laser pointer indicates by flashing that the value is falling below the dew point and in this way shows you the wall surface affected. Please take into account that the increasing measuring distance also increases the measuring spot size of the infrared sensor on the wall. At a distance of 1 m, the measuring spot has a diameter of approx. 10 cm. At a distance of 2 m, the measuring spot diameter is approx. 20 cm. The on-demand laser aiming aid always indicates the measuring spot centre.

Compensation moisture measurement

Compensation moisture measurement

By climate measurements in drill holes or hollow spaces it is also possible to determine the moisture content of building materials. If the actual moisture content corresponds to the value of the sorption isotherms, the building material is in a state of balance from a structural-physical point of view. If the moisture content is above this value, this indicates that there is building moisture.
