Fujifilm Thermoscale® - Tactile Surface Temperature Indicating Film

Fujifilm Prescale Film Placed on a Battery Lamination Press

Thermoscale is a unique tool that indicates temperature level and distribution between any two contacting surfaces. The most unique quality of Thermoscale is that is goes where no other IR camera or temperature gauge can ever go - on the surface of the heated object and in between two contacting surfaces!

Making the invisible visible

Thermoscale is a thin (similar to a sheet of paper) flexible film-like material that actually changes color when it comes in contact with elevated temperature. The color change is both instantaneous and permanent and allows the user to read and interpret the color to get a fix on precisely what temperature has been reached at all points across the heated surface. Physically similar to Litmus paper the color that Thermoscale turns is directly proportional to the temperature level.

How it works

Heat melts the developer and makes the microcapsule walls permeable, allowing developer to enter the microcapsules, where it reacts with the color-forming agent to produce color.
