Macrostructure Electrolytic Etching Device CME-2000X
Large‑current electrolytic etching equipment for macrostructure inspection of steel, aluminum alloy and metal materials, low acid concentration, no heating, high efficiency and good repeatability.
The Macrostructure Electrolytic Etching Device CME-2000X adopts electrolytic etching technology for macrostructure display of metal materials. Compared with traditional hot acid etching, it uses only half hydrochloric acid concentration, requires no heating, greatly reduces acid fume volatilization and improves working environment. The power control unit and etching tank can be placed separately at long distance to protect operators and electrical parts. It supports simultaneous multi‑sample batch processing with high efficiency and strong repeatability, ideal for factories, labs and inspection institutions with high sample throughput.
2. Key Selling Points
- Electrolytic etching method: only half acid concentration compared with hot acid etching.
- No heating required, low working temperature, less acid volatilization, safer environment.
- Instant operation: power on and start etching without preheating, save time.
- Can place multiple rows of samples at the same time, high batch processing efficiency.
- Power control unit and etching tank support long‑distance separation.
- Stable etching performance, high result repeatability, good consistency.
- Touch screen + single‑chip microcomputer + silicon controlled control, stable and reliable.
- Timing function with buzzer alarm upon completion.
- Suitable for high‑volume sample testing in steel mills, foundries and quality labs.
- Outer dimensions can be customized according to customer requirements.
