Basics of temperature and thermometer calibration


Temperature measurement and calibration often go wrong. You will be introduced to common errors in temperature measurement and calibration. You will get a better insight into what makes a thermometer so special. This course is one of our courses that you partly follow through e-learning.

Basics of measurement, metrology, traceability and uncertainty


This course offers help to those planning to set up a thorough measurement or calibration system in your company, regardless of what you are going to measure or calibrate. This is also the ideal course for new colleagues not yet familiar with traceability or measurement requirements of ISO/IEC 17025, such as uncertainty. An important part of ISO/IEC 17025 is measurement uncertainty. Moreover one of the most important principles of measurement is that an uncertainty is to be calculated by those who do the measurements. This course exist of three modules and is set up as a blended-learning-course.


  • Accreditation systems and Conformity Assessment Bodies (RvA, UKAS, DAkkS, COFRAC, INAB, NVLAB, A2LA ..)
  • Units and Quantities
  • International and national traceability
  • Measurement standards and written standards
  • Certificates, calibration, validation, verification, audit, certification, interlaboratory comparisons
  • How do I see if certificates are acceptable for traceability
  • ISO/IEC 17025:2017 versus ISO 9001:2008
  • ISO/IEC 17025:2017 versus ISO/IEC 17025:2005 metrology-wise: decision rule
  • Accredited or ISO 9001 certified, what is the difference?
  • Complaints
  • Uncertainty versus Error
  • Calibration and uncertainty
  • Rounding of numbers
  • Uncertainty contributions in practice
  • What instruments need calibration: selection by means of an expert diagram
  • How often do instruments need calibration: don't spend more than needed!
  • The use of a certificate and measurement specifications for an uncertainty evaluation
  • Examples and exercises of measurement problems in practice
  • The approach on uncertainty is based on EA 4/02, on UKAS M3003, on the NIST uncertainty guide and the GUM


  • The course consists of three modules, the first of which is an E-learning module that you start with on your own leasure preceding the course day. You will work some hours (have a day) by self-study on your own computer.
  • The second module is a class-room training with a very experienced teacher. You will participate actively to examples related to simple measurements and will learn the basics of uncertainty and develop your skills to decide what needs to be calibrated and how often and what to look at when interpreting calibration certificates.
  • The third part of this course is a further E-learning module where you will study the course subjects through further background information and you will do a test. The aim of this test is to skill you in actively using the information you learned during the course. It is our experience that this helps you to digest the course information and allows you to use what you learned afterwards. For this reason you can repeat the test a few times if you find that the score is too low. The test will then consist of similar, but different questions. 
  • You will receive a diploma if your score is 70% or more, and a certificate of participation otherwise. 
  • This combination of course approaches is called blended learning and is found to be more effective than passive learning methods.

This course is for

  • Starting instrument engineers and calibration technicians in a test or calibration department
  • All those involved in measurement who need to prove tracebility for ISO 9001, EN 15189, ISO 16949, HACCP, GLP, GMP...

After this course

  • You can decide on the future of the measurement quality in your company / laboratory / institute
  • You are fammiliar with cost efficienty on the required calibrations of your equipment
  • You can use specifications and certificates
  • You will know how to verify the uncertainty of a measurement or estimate it competently
  • You can be further qualified in metrology by atttending our other courses such as measurement uncertainty


  • This course consists of an initial Elearning module that takes you half a day; a subsequent one-day course by an experienced teacher and and a further E-learning module including a test taking you a further half a day.
  • Costs include lunch, course documentation (powerpoint-sheets with complimentary text) and a certificate with your test result.
  • Ask for our current prices.
  • Teacher is Martin De Groot (NL), Dave Ayres (UK) or Tom Wiant (US)

When & where


Control and traceability of balances, pipettes and thermometers in laboratories


Which equipment do you need to calibrate in a test or medical laboratory and how often? Based on which rules do you make this choice? You will become familiar with the calibration of pipettes, balances and thermometers by taking some measurements yourself, the background will be explained to you. We give this course in collaboration with QAducation, which also organizes the course.


In this course you shall learn all about EN 45501 and related guidelines.

Basics humidity measurement and calibration


Rotting food, fungus on paintings, consense in green houses... There are dozens of situations where humidity of air is very important. This course helps you to measure and understand humidity.
