Measuring physical and chemical parameters e.g. temp., resistance-conductivity or humidity, in building materials

摘要

The screw-probe (1) which fits into a plug (2) in a predrilled hole (3) in multi-layered building systems, such as floors or walls, integrates the sensors for measuring resistance, conductivity, temp. and moisture content at any chosen layer of the construction. It can be used in stone, concrete, cement or any similar construction substance. By the use of an integrated temp. sensor, the probe compensates automatically for this factor in taking measurements which are temp.-dependent. Consequently, results are accurate and reproducible. The probes are clean and simple to use, durable and reusable.
