THE PUBLICATION
About MeasureProof
A publication about what a workshop length check can establish.
What does this publication explain?
MeasureProof publishes UK English notes on workshop checks of 0–25 mm outside micrometers and digital calipers against gauge blocks. The notes are for small machine shops, model engineers and incoming inspection. These pages are source-based explanations. External authors’ measurements were not performed for this publication. MeasureProof is not a certification body or an accredited calibration laboratory.

MeasureProof is operated by RETRETO NEXT LIMITED. Company No. 15166864, registered in England and Wales. Registered office: Office 8929, 182-184 High Street North, East Ham, London E6 2JA. Companies House record. Articles are attributed to MeasureProof. The attribution names the publication, not a named metrologist or an accredited laboratory.
The operator also owns related instrument retail sites. The disclosure policy explains how that relationship is presented.
Where does the evidence come from?
The notes link original workshop publications, manufacturer documentation and official UK guidance, and the different role of each source stays visible. The methods page sets out what is required before a result is called an original test. A source check is not a measurement made by this publication.
