7-inch touch screen operation control.

(b) The voltage, current range, which can satisfy both the polishing and corrosive of the materials;

(b) The method of working for constant currents and constant voltage;

Direct current 0~100V / 0~6A, current/voltage value customised;

(a) The power, current and primary and fine-adjusted switching functions that allow for the accurate and stable setting of the current values of voltage;

(b) voltage currents are adjusted to show two decimal places;

Low-telecom-striped, high-stable;

(b) Overpressure of power, overheating and under-pressure protection of municipal electricity inputs;

Controlled area of the sample for polishing/coloration (15 mm, 20 mm, 30 mm) in the diameter of the sample;

Control of polishing/corrosion working hours;

The mixer ensures that the polish/corrosive medium is even and that the surface environment of the sample is consistent;

Work voltage, currents can be entered into the computer to facilitate further data analysis and research (option: RS485 connection optionally).
