Start by understanding what you measure.

Guides and model candidates

Method explanations include both suitable applications and limitations. Model candidates link to manufacturer references or catalogs whose specifications were confirmed by the site operator. Check the conditions for the selected configuration; listings do not guarantee availability, price or sample performance.

How the finder works

The finder compares your description and selected conditions using defined matching rules. It considers the substrate, layer, interval, access, contact and permitted damage. Missing or ambiguous information is flagged for clarification. The recommendation feature does not send your application description to a generative AI service.

Editorial approach and evidence

Public guides explain the measurement task, selection reasoning, limitations and sample questions. AI assistance may be used in drafting; no independent testing or manufacturer review is implied. Calculations and application examples distinguish an illustrative assumption from an observed result.

If a specification appears inconsistent, compare the linked manufacturer reference and the exact probe or option first. Only authorized operators can update catalog records, with source and specification confirmation.

Product photographs

Selected guides and models feature photographs from DeFelsko’s official image gallery. Captions identify the product family and source; model descriptions explain probe and option differences. The photographs do not imply manufacturer endorsement of, or affiliation with, thickness.biz.

Advertising and recommendations

Advertising is currently paused. Advertising settings do not change method suitability or recommendation ranking. Search, input, empty-result and management screens contain no ad placements.
