Measuring device for relative humidity in concrete sample, comprises fixed part with cavity for sample or reference cell, and rotatable part with cavity for humidity sensor

摘要

The fixed part (1) of the device contains a cavity (15) for the sample (3) or a reference cell (4) for generating air with a known relative humidity. The rotatable part (2) of the device contains a cavity (16) for the relative humidity sensor (5). The device comprises a block with a rotatable part which can be rotated about the block central axis (8) relative to the fixed part.
