This is the operation manual for the CT-3 electrolytic coating thickness meter, covering safety precautions, specifications, structure, measurement…
The CT-3 is an electrolytic coating thickness meter designed to measure the thickness of metal plating on substrates. The device operates based on Faraday's law, where the thickness of the coating is determined by the time required to completely electrolyze the metal layer. It features a constant current source, an electrolytic end-point detection system, and a control system with various adjustment knobs for sensitivity, range, and probe selection. The manual details the composition of the measurement stand, including the electrolytic cell, rubber probes, and stirring device, and explains how to assemble and use them correctly. This manual is written in Chinese.

The device uses Faraday's law, where thickness is determined by the time required to completely electrolyze the metal layer when current and area are fixed.
The electrolyte is generally used for about 6 hours; it should be replaced when measurement becomes unstable.
No, the device must not be disassembled or repaired without the manufacturer's instruction to avoid electric shock or injury.
