Areas of application/material types specific to the measuring heads:

Application-specific measuring heads, which can be used with both measuring devices, are available for various areas of application.

This provides various possibilities for data acquisition and processing, which extend as far as the graphical display of the distribution of moisture in measurement objects. In many cases only this grid moisture measurement can really provide the necessary information with regard to the moisture content of objects.

Individual measurements can be carried out quickly with all moist sensors. The measuring devices are equipped with an energy-saving standby logic, with which you can switch on the measuring head circuitry for about half a second as required.

This rapid measurement option enables you to record many measured values in a short space of time.

Characteristics of the available microwave measuring heads

Moist-R1Moist-PMoist-R2Moist-DMoist-SMoist-Endo
Radiating applicator for moisture measurements in the outer material layers.Radiating applicator for moisture measurements in the volume or core of a sample. Irregularities in the material can be compensated due to the large measurement volume.Stray field applicator for moisture measurements in the outer and central material layers.Radiating applicator for moisture measurements in the central material layers.Radiating applicator for moisture measurements in deep material layers. Primarily suited for relative measurements in very thick materials and structures.Penetration applicator for moisture measurements deep inside the measured object.

All measuring heads are powered by the Moist hand-held measuring device. The possibility of material-specific calibration enables exact and reproducible moisture measurements even under difficult usage conditions.
