Abstract
The paper describes and evaluates five different instruments for
measuring the relative humidity (RH) in concrete structures. The
instruments work according to different principles. The evaluation
of the instruments includes tests for linearity, drift over time,
hysteresis and repeatability, and it is performed by use of
saturated salt solutions in the laboratory. Further, the five
different instruments are placed in the same concrete, and the
instruments readings are followed during drying of the concrete
for 43 days. The laboratory tests and the measurements in the
concrete show that most of the instruments work well.
