OPTIMU, the metrology software

As simple as effective, OPTIMU has become the leading software of Metrology. Acknowledged for its quality and usability, it meets all the needs of management tools, calibration and periodicity optimization.

Objective: save time, control risks and rationalize costs


More than a measuring instrument management software

Already used by more than 2,000 industrials and Cofrac laboratories, OPTIMU facilitates compliance management of measuring and monitoring instruments, and optimizes calibrations, in-house or subcontracted out.

Objective: save time, increase productivity and streamline costs!


A modular and scalable solution supporting metrologists

Friendly and comprehensive, the OPTIMU software meets all the needs of the metrology service and can be customized to different user profiles. The OPTIMU software is made of several modules which can be acquired as the metrology service evolves to better fulfill your expectations.

Objective: to gradually develop and optimize the metrology function

A deployment with ease

With its large range of services and its acknowlegded expertise, our support teams provide guidance and a set of complementary services to facilitate the implementation of OPTIMU software in your business, on your network or in a hosted version 100% online

Objective: quickly enjoy a turnkey metrology solution, without any IT investment

Functionalities and Modules
Measuring Instrument Management Keep track of your measuring instruments.

Manage your measuring instruments with ease and efficiency…

A powerful tool for any metrologists who want to easily manage their instruments and save time using indicators and custom alerts

  • Choose indicators on the home page for a quick and easy analysis
  • Simplify intervention calls and interactions with calibration providers
  • Identify any non-compliant instruments or out of tolerance for effective decision making
  • Follow the progress and detect instrument drift

… for stress-free audits

  • Quick and easy management of the measuring equipments
  • Compliance with ISO 9001, 10012, IATF 16949, 9100, 13485, 17025, 15189, …
  • Creation of delivery notes, shipping notes, and labels
  • Automatic email with various indicators (late instruments, interventions to do, monthly / annual budgets, ...)
  • Input / output management and equipment reservations
  • Traceability using bar codes
  • Interaction with many calibration laboratories

Make your calibrations easier

OPTIMU meets the needs of in-house and / or accredited laboratories (Cofrac in France, SCS in Switzerland and ACCREDIA in Italy), who have chosen OPTIMU for:

  • Its technical library: calculation of the theoretical values ​​for gauge (standard, manufacturer, or added customer requirements)
  • Calibration of all types of instruments
  • Real-time declaration of conformity during calibration using standard, manufacturer or customer requirements
  • Automatic editing of calibration documentation (CC / VC) with or without accreditation
  • Ability to take into account the uncertainty in the declaration of conformity (ISO 14253-1)
  • Traceability of the standard gages and use of the corrections upon the values provided by the standard gages
  • Offline calibrations , performing calibration campaigns on client sites in a simple and intuitive way

Choose the most suitable optimization method for your instruments

The optimization module is natively included in the software to allow industrials the use of calibration periodicity optimization methods found in the FD X07-014 booklet

  • Implementation of the OPPERET method, to take into account various impacting factors
  • Drift method to anticipate the wear limit from historical results
  • Periodicity ratio method to determine the optimum date of the next calibration, i.e. based on the impact of the instrument on the process measurement uncertainty
