เครื่องวัดความชื้นกระดาษแบบพกพา Paper Moisture Meter รุ่น MD-916 ย่านวัด 2% -40% แม่นยำ ±0.5%

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.

Paper Moisture Meters is specially for measuring paper moisture. The characteristics of the paper that absorb and evaporate moisture. This directly affects the elasticity and contraction of the fibers within the paper. The paper is bent and deformed. The paper in normal environment has a moisture content of 5 to 7% per square

Absolute humidity does not take into consideration temperature, while relative humidity relies on temperature and is expressed as a percentage of the total amount of moisture possible at the current temperature. Thus, many paper moisture meter devices feature automatic temperature compensation (ATC).

For paper producers, paper manufacturers, paper mills and others in the pulp and paper industry, moisture and humidity control is essential, especially during the production process, as excessive moisture can lead to warming of the paper rolls. A paper moisture meter can be used to detect moisture streaks during the paper production process as well as to identify optimal drying times.

Regardless of whether paper is stored in paper rolls in paper converting plants or stacked in sheets and paper bales in commercial printing warehouses, the porous surface of paper gradually takes in moisture relative to the humidity of the surrounding environment.

This moisture can be problematic, as too much moisture can cause curling, buckling or the formation of waves in otherwise flat paper products. Moisture also can prevent inks, dyes, paints and coatings from covering and saturating paper properly during printing and processing.
