*Discontinued* Two-Tank Model Etching Machine (ES-850M)

• Discontinued

*Discontinued* Microprocessor-controlled from etching to rinsing

• Original PCB Production Tools
• Etching Machine
• Rigid PVC

Prices were revised effective August 1, 2025.

The two-tank system (etching tank + rinse tank) allows for immediate rinsing after etching. Since liquid temperature settings and conveyor speed are microprocessor-controlled, reproducibility under identical conditions is ensured.

The warranty period (including maintenance) will end 7 years from the delivery date or at the end of fiscal year 2028, whichever comes first.

There are no replacement or successor models available after sales end.
