The near-infrared in-line moisture meter uses a high-precision infrared filter mounted on a runner and imported motors that allow reference and measurement light to pass alternately through the filter.
The reserved beam is then focused on the sample being tested.
First the reference light is projected onto the sample, and then the measurement light is projected onto the sample.
These two timed pulses of light energy are reflected back to a detector and converted into two electrical signals in turn.
These two signals combine to form a ratio, and since this ratio is related to the moisture content of the substance, the moisture can be measured.
