Microcomputer control from etching to rinsing

Prices have been revised effective July 1, 2023.

The two-tank system consisting of an etching tank and a rinsing tank allows for prompt rinsing after etching. The liquid temperature setting and conveyor transfer speed are controlled by a microcomputer, so reproducibility can be maintained under the same conditions.
