Coulometric Coating Thickness Tester for Chrome and Nickel Plating

Coulometric thickness tester that dissolves a small area of plating anodically to measure layer thickness of chrome, nickel and copper on taps and fittings. Used by plating shops and bathware factories for coating control.

Specification

A small electrolyte cell is placed on the plated surface and the metal layer is stripped at a constant current while voltage is monitored. The thickness is calculated from the dissolution time. It gives accurate results on small and curved parts.

Features

• Measures single and multilayer coatings
• Test cell with 1 to 2 mm aperture
• Stored electrolyte and coating programmes
• Digital display and thermal printer option
• Good accuracy on curved faucet bodies
