Compare Our Calibration with Other Laboratories

ISO17025 includes requirements for accredited laboratories to regularly compare their calibration with other laboratories.  Being awarded ISO/IEC 17025 acts as proof of your laboratory’s true competency.  We know that as a calibration laboratory, we must stay informed about new technological and legal developments in the industry.  Proving we are technically competent and have demonstrated that we are technically proficient and able to produce precise and accurate test and calibration data. MBW CALIBRATION™ routinely compares their laboratory across many comparisons and criteria through Euramet.   It matters that we maintain high competency and data integrity throughout our laboratory quality management system (QMS).  We are experts and can perform a full range of international standards at our fully accredited laboratories.  Our ISO 17025 accredited labs can help you to achieve product compliance.

  • Compliance with regulatory and safety requirements
  • Traceability of measurements and calibrations to national standards
  • Technical competence of staff
  • Maintenance of test equipment
  • Validity and appropriateness of test methods
  • Appropriate handling and transportation of test items
  • Quality of testing environment and sampling
  • Meeting quality requirements of specialized customer

Examples of comparisons:


  • Comparison of humidity standards: dew and frost point temperatures 2003 – 2010
  • Comparison Type Field: Key comparison in thermometry and humidity
  • Temperature: -50 °C to 20 °C
  • Status: Approved for equivalence, results available

MBW CALIBRATION chilled mirror analyzers are most commonly used as the transfer standard to maintain traceability.  As a Swiss Designated Institute for Hygrometry (DI), we participate in different activities, working groups, committees etc. related to metrology. 


We perform humidity calibration and MBW is ISO17025 certified.  We are leaders in humidity standards. Our chilled mirror analyzers provide long-term stability to achieve lower uncertainty of calibration (CMC) levels.


MBW CALIBRATION is an active associate of EURAMET. EURAMET is responsible for the execution of the European Metrology Research Programme (EMRP) whose mission is to develop and disseminate an integrated, cost-effective and internationally competitive measurement infrastructure for Europe.
