What your metallography lab actually checks
Metallography where the part is
Some components can't be sectioned or brought to the lab. The battery-powered QETCH 100 M electrolytically polishes and etches a surface on site — so failure analysis and microstructure checks happen at the part, not weeks later.
An applications engineer on the line
Method setup, consumable selection and troubleshooting from engineers who run sample prep and materials characterization in-house. Sub-4h reply, NDA standard.
The QATM QETCH 100 M is a mobile, battery-supplied electrolytic polisher and etcher. Compact and robust, it brings electrolytic surface preparation to work outside the lab — on-site failure analysis, large components, field inspection — with simple operation and high functionality.
Why labs choose the QETCH 100 M
Electrolytic polishing and etching, anywhere.
Battery-powered
No mains needed — electrolytic polishing and etching on components that can’t come to the lab.
On-site metallography
A ~Ø 9 mm polishing area prepares a surface in place for replica or portable-microscope inspection.
Rugged & protected
Epoxy-coated aluminium housing meets high demands on stability; sensitive parts protected for transport.
Field-ready
Handle and carrying strap for maximum comfort in local operation.
