ABSTRACT:
Moisture testing instruments for use in heaped, loose material include a neutron source and a detector. The instrument is calibrated by duplicating the test volume as calibrating container and by radiometrically as well as gravimetrically detecting the moisture content, which is varied either by evaporation while the moisture is spread or by adding determined quantities of water.
