Drying Time Recorder Measures and Records Drying
Times of all types of Coatings, Adhesives and More
Meets ASTM D5895
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-inch (10 mm) ball stylus and a counterweight 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 the 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.
The new design display is now even easier to read and positioned on
an angle to make for easy viewing.
