Structure and principle
Structure of Prescale
There are two types of Prescale: the two-sheet type and the mono-sheet type. The two-sheet type is composed of two films of which are respectively coated with color-forming material and color-developing material. This type is used by placing the sides coated with the chemical agents over each other. The mono-sheet type is a film with a single base film with a coating of color-forming material and developer.
How Prescale works
The microcapsules in the color-forming layer are broken by pressure, and the colorless dye is absorbed into the developer, causing a chemical reaction to produce a red color. The microcapsules containing the color-forming material are adjusted to varying sizes and strengths, and is coated uniformly, producing a color density that corresponds to the amount of pressure.
By checking the standard chart, the pressure value can be confirmed visually.

How to use Prescale
1)【Illustration】 How to use
Cut the Prescale or Prescale Sheets into the shapes needed for measurement.
Insert the Prescale between the surfaces to be measured.
Apply normal operating pressure.
Remove the Prescale.
You can now see the pressure and its distribution.
Use the special scanner to scan the colorized Prescale sheet.
By selecting measurement conditions, you can take measurements of the pressure values of entire objects, partial sections, and precise points. The data export function can be used to export data in Excel format, and three-dimensional image analysis can be performed by using 3D analysis software.
