Tactilus vs. Prescale

Analogy   Like a "Movie"   Like a "Photograph"
Product Name  
Suited For   Your two surfaces contact and continue to move and require pressure data capture throughout an interval or time.   Your two surfaces contact and you simply require to get a "snapshot" of the maximum contact pressure between those two surfaces.
