New design display is now easier to read, the display is positioned on an angle to make for easy viewing.

 


Features

The Gardco Quadracycle Drying Time Recorder consists of a stepper motormounted 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. Can be used directly on any substrate.

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. Set the arm to equilibrium by adjusting the rear counterweight before placing the 12 gram weight on top of the ball shaft.
  3. Apply the coating to your test panel using a Gardco Microm Film Applicator or equivalent 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.
This unit will operate in temperatures from 32°F to 120°F (0-50°C), 5-95% humidity (no condensing) however, it is not recommended for oven use. For oven use, the GARDCO Spring Motor Drive Drying Time Recorder should be considered.
