Digital Cupping Tester is designed to evaluate the elongation and deformation of lacquers and other protective coatings on metal substrates. A punch is applied on the uncoated side of a metal panel to evaluate crack resistance and detachment of paint from the metal substrate of coated surface. The sample panel max. 1.25mm thick×70 mm width, coated min.0.03mm)is clamped by an upper wheel and manually cupped by a ф20mm hemispherical indenter onto a ф27mm die by a drive wheel. The depth to cause failure is indicated on a precise digital display. The results can be easily observed with an illuminated magnifier.
The Digital Cupping Tester KT 237 compliance with ISO 1520、BS 3900 Part 4、DIN 1502 etc,. It integrates an automatic coordinate positioning system: machine can memorize the home position after being zeroed, and locate the plugs position automatically. The usual error caused by replacement or wobble can be eliminated. It has a high precise position sensor: the minimum division value of the depression depth can reach 0.01mm. It can be used for every kind of substrate, and the maximum pressure can reach 2500N. The coordinate position of the plug can be zeroed manually and can be memorized while it is cold. Easy -handling. It comes complete with the cupping tester, indenter, zero plate, magnifier glass, batteries and user manual.
