An analytical balance is a weighing instrument that is used in analytical-chemical laboratories for the accurate weighing of substances. The accuracy of an analytical balance is, depending on the design, range and type, 1 mg to 0.001 mg. Due to the accuracy, an analytical balance is very sensitive to environmental factors such as draft, temperature and vibrations. It is important that analytical balances are properly calibrated and possibly adjusted. An accurate weighting ensures that the quality of the end product is stable and of a high level. Here you will learn everything about calibration of weighing instruments and analytical balances according to a recent technical guideline for the calibration of weighing instruments prepared by the European Association of National Metrology Institutes.

In one day you will become acquainted with common errors when weighing substances and calibrating weighing instruments. You get a better insight into which issues influence the weighing and calibration of a weighing instrument. This course is subdivided into three modules and is set up as a blended learning model.


  • Use of reference mass pieces
  • Weighing up substances and materials
  • Estemating the influence of environmental conditions
  • Calculating the uncertainty
  • Calibrating weighing equipment and the use of graduating technology
  • The preparation of calibration certificates


- The course starts with an e-learning module that you can use to get started prior to the course day. You then work through the self-study topics in a short time and provide some answers to questions.
- The second module is the course day.
Module 3 is a test that you must do within a set time. You have multiple attempts.

This course is for

  • Technical staff from analytical laboratories
  • Laboratories and users of weighing equipment
  • Calibration staff
  • Employees of companies where weighing equipment is calibrated and maintained

After this course

  • You can perform a weighting in an adequate manner
  • You can independently check and calibrate weighing instruments
  • You can estimate the influence of environmental conditions
  • You can perform a simple uncertainty calculation
  • You can understand and prepare a calibration certificateTechnische medewerkers van analytische laboratoria


  • The course takes 1 day of contact education, an e-learning program in advance of approximately 1 hour and a test of approximately 2 hours.
  • Costs €725,- for lunch and coffee / tea are provided, excluding VAT
  • You will receive either a diploma with a list of marks after sufficient completion of the test or a declaration of participation
  • The course is given based on the EURAMET Calibration Guideline No. 18, guidelines for Calibration of Non-Automatic Weighing Instruments, TC-M, Version 4.0, 11/2015
  • Teacher is Mr. J. C.G.A. Verbeek
