Drying Time Recorder Model 504-V

The Model 504 drying recorder automatically registers and records the drying behaviour of paints and similar coatings. This device consists of a metal housing with cover plate. This cover plate also serves as a support surface for 6 glass strips measuring 300 x 25 mm, on which the coatings to be tested have been applied. The six testing needles are attached to a steel holding fixture. The power switch and the rotary knob for setting the running time (6, 12 or 24 hours) are located on the side. The Drying Time Recorder comes with variable testing speeds. This device has a choice of 20 pre-programmed running times from 7.5 minutes to 96 hours. (Other running times are available on request)
