Paper Moisture Meter

A paper moisture meter measures the humidity of paper and paper products. Use of a paper moisture meter can prevent costly damages resulting from paper expansion or shrinking. A paper moisture meter determines paper moisture content based on either absolute humidity or relative humidity.Moisture content gets measured as relative humidity (RH), and most papers are designed to be stable at 45-55% RH in a 72°F environment. Typically, manufacturers produce paper to an absolute moisture content between 4.0 and 6.0%, meaning water makes up 4 to 6% of the paper's total weight.
