EP - 3000 electrolytic polishing corrosion instrument

                                                        EP-3000 electrolytic polishing corrosion tester

The EP-3000 electrolytic polishing corrosion tester is a high voltage and high current metallographic sample preparation instrument that integrates electrolytic polishing and corrosion functions. Suitable for use in laboratories such as factories, colleges, and research institutions.

This equipment utilizes electrochemical principles for the preparation of metallographic samples, can also be used for polishing metallographic samples, and can also be used for corrosion of metallographic samples. It has the advantages of fast sample preparation, good repeatability, and no mechanical deformation layer. It is an ideal equipment for preparing metallographic samples of non-ferrous metals, steel, and especially stainless steel.

Main features：

1. Set parameters on the touch screen, display voltage time, current time curves, and temperature time curves, and export experimental data from a USB flash drive.

2. Current and voltage scanning, automatic measurement of polarization curve: used to confirm the specific voltage and current for electrolysis or polishing. After generating the curve, it is used to obtain the optimal parameters (options) for corrosion and polishing that are suitable for the material.

3. Realize constant current and constant voltage working mode;

4. DC 0-60V/0-20A (or 0-100V/0-12A); Current/voltage values can be customized;

5. Accurate and stable setting of current value, current regulation, accuracy to three decimal places, current accuracy: 0.001A;

6. Accurate and stable set voltage value, voltage regulation, accuracy to two decimal places, voltage accuracy: 0.01V

7. The working voltage and current can be input into the computer for further data analysis and research (options: RS232, RS485, wireless connection, one of the three connection methods connected to the computer).

8. Protection against overvoltage, overheating, and overvoltage and undervoltage of mains input;

9. Can control the polishing/corrosion area of the sample (sample cover opening diameter 10mm, 15mm, 20mm);

10. Set and control polishing/corrosion working hours;

11. Real time digital display of solution temperature, automatic alarm when exceeding the set temperature (optional); Automatically turn on the cooling device (option);

12. The stirring device ensures uniform polishing/corrosion medium and consistent surface environment of the sample.
