Investigation of Material Properties of POM-C with Regard to its Suitability as a Casing Material for a Time Domain Transmission Profile Probe

The objective of the PROFILE TDT project is to develop a robust, low-cost profile probe with high accuracy of <;2% for longtime observations of soil moisture, salinity and temperature. The probe works with a modified Time Domain Transmission Technique, which was invented by our cooperation partner the Bohdan Dobrzaiiski Institute of Agrophysics. Different materials were tested regarding their water absorption and its influence on the signal, on both laboratory and field scale. Different materials were tested regarding their water absorption and its influence on the signal, on both laboratory and field scale. Literature research and our own tests have shown that POM-C delivers satisfying results.
