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.

Instructions for Use
1. Attach the arm and ball assembly to the motor shaft by way of the hex screw. Once tightened to
the desired position do not forcefully move the arm and ball position without loosening as this can
cause damage to the gearbox assembly.
2. Balane the arm by adjusting the rear counterweight before placing the 12 gram weight on the ball
shaft.
3. Apply the coating to your test panel using a Gardco Microm Film Applicator or other wet film
applicator.
4. Immediately place the Drying Time Recorder on your test panel and lower the clean 3/8 in.
weighted Teflon stylus gently into position.
5. Select the desired drying time and the stylus will then begin to be drawn along the test panel.
6. After the selected time cycle is complete the Drying time recorder will automatically stop. Evaluate
the test panel using the supplied Time Template to determine the stages of drying time.
7. Place the clear Time Template over the circular area scribed by stylus
and note appropriate scale number of minutes or hours required for
the film to cure, the character of the track by the 3/8 inch Teflon ball
stylus relate
to the drying of the film (Reference ASTM D5895).
8. Record the results and if desired, record the temperature,
humidity and the wet film thickness as these factors are
important in considering the drying time of films.
