Frequently Asked Questions
What materials can the QE-UH100 test?
It is primarily designed for metals, including steel, stainless steel, cast materials and non-ferrous alloys when an appropriate calibration is available.
Does the tester damage the test surface?
UCI testing produces a very small indentation and is generally considered minimally destructive.
Can it test thin components?
Yes. The optional low-force H probe is recommended for thin, polished or coated components. Suitability depends on material thickness and support conditions.
Does it require surface preparation?
The measurement area should be clean, stable and sufficiently smooth. Coarse or oxidized surfaces may require grinding or polishing.
Can test results be transferred to a computer?
Yes. Stored measurements can be transferred using the supplied USB connection.
