Pressure Reactive Film
Johnson and Allen supply Fuji brand Prescale - A pressure sensitive film that changes colour depending on the forces applied to it. The level of pressure is indicated by the density of the colour change. A useful product with many applications in the NDT industry and in general engineering.
