[en] One near infrared (NIR) reflectance and five dielectric moisture meters were tested for their capability of measuring moisture content
(MC) in solid biofuels. Ninety-eight samples were tested at up to eight moisture levels covering the MC range from fresh fuel to
approximately 10% MC (w.b.). The fuel types ranged from typical solid biofuels such as coniferous and deciduous wood chips over short
rotation coppice (SRC) to sunflower seed and olive stones. The most promising calibrations were obtained with the NIR reflection
method and two dielectric devices where the sample is placed in a container integrated in the device. The calibration equations developed
show that there is a profound influence from both laboratory and fuel type. It is suggested that individual calibrations that are based on
the specific fuel types used at the individual heating plant could be applied.
