Pressure Measurement Film Check the pressure distribution and uniformity clearly. No special equipment or device. Pressure Measurement Film: Xiaoyue pressure sensitive film is composed by a A film which is coated with a particular micro encapsulated color forming material, and by a C film, which is coated with a specific color developing material. Used in conjunction, the two films should be placed with the coated (rough and opaque) surface facing each other. When the micro encapsulate under stress, the color former will react chemically with color-developing agent and display rosy.
