NULLPOINT METROLOGY

Measurement assurance & test validation

Zero the error. Keep the truth.

Nullpoint Metrology makes your test results trustworthy, then makes them repeatable. We find where measurement error comes from, prove how good a method is, and give you documentation an auditor will accept.

When to call us

Your numbers are only as good as the measurement behind them

Two stations, two answers

Test stations, sites, or your supplier and your customer measure the same part and disagree.

An auditor wants evidence

ISO/IEC 17025 or ISO 13485 asks for an uncertainty budget or a validated test method you don't have yet.

A new product needs a test

You need a method designed properly from the start, with acceptance criteria you can defend.

Results drift

Readings change over time and nobody can tell whether the product or the measurement moved.

Services

Fixed scope, fixed price, in USD

Most work is delivered remotely from your data and setup description. On-site work is available on request.

What you receive

An uncertainty budget tells you what to fix first

Every source of error is quantified and combined following the GUM method. The contribution column shows where your effort pays off.

In this illustrative example, repeatability drives almost two thirds of the uncertainty. Improving fixturing and averaging would do more than buying a better reference.

How it works

From first call to a defensible result

  1. Free 20-minute call

    You describe the measurement and the problem. We tell you honestly whether we can help.

  2. Fixed proposal

    A short scope with deliverables, timeline and a fixed USD price. An NDA first if you need one.

  3. Analysis

    We work from your data, setup details and, where needed, a site visit or video session with your team.

  4. Report and handover

    Clear findings, the fixes in priority order, and documentation you can hand to an auditor or customer.
