Prescale™ Pressure Indicating Film Specifications
There are two types of Prescale™ film: two-sheet and mono-sheet.
Two-sheet Prescale Film (Extreme Low pressure through Low pressure):
Composed of
two polyester bases, A-Film and C-Film. A-Film is coated with a micro-encapsulated
color-forming material, and a C-Film, which is coated with a
color-developing material. The A-Film and C-Film must be positioned
with the coated sides facing each other.
Mono-sheet Prescale Film (Medium through Super High pressure): The color-developing material is coated on a polyester base, with the micro-encapsulated
color-forming material layered on top.
