The Drying Time recorder consists of a stepper motor mounted on a rubber tipped tripod. The arm and ball assembly has a counter-poised vertical stylus consisting of a Teflon 3/8 in. (10 mm) ball stylus and a counter weight to adjust to zero. The Teflon stylus typically under a 12g load (weight supplied) is moved in a 360 degree arc at a pre-selected fixed speed.

A shaft arm with Teflon® ball scriber produces a 2" diameter circular path. Drying time is observed and recorded as the ball penetrates the film and produces a circular groove over a period of time. After drying is completed a clear plastic time template is placed over the area so that the drying time record can be converted into minutes or hours.
