It is available in thin plastic sheets of 4 mils or 8 mils and comes in eight pressure ranges from 7.2 PSI to 28 PSI. The film is placed between contacting and mating surfaces to obtain the contact surface pressure.

The film changes color according to the amount of pressure applied, and a measurement is obtained by matching the color against a correlation chart. Flexible enough to conform to various spaces, the film can measure pressures up to 43,200 PSI.
