The ISMA is a handheld device used to quickly determine the relative moisture of the shell of a softgel capsule. Moisture content is determined indirectly by measuring the electrical resistance through the softgel shell. As the moisture content of the shell increases, resistance decreases. This unique relationship allows moisture levels to be determined nondestructively in a few seconds. The electrical resistance of water is roughly one billion times higher than most metals and therefore requires precise electronics to measure the high resistance through a softgel shell.
A quick and easy alternative to the softgel LOD test
Measures moisture within 5 seconds accuracy to one decimal point
Measures moisture content from 5% to 20%
Cup volume holds approximately fifty #10 oval softgels
