The 14th SMIIC MC Training within the SMIIC MC Work Plan 2024 – 2026 V1 was the The Importance of pH Measurements and How to Calibrate Devices that Measure pH  that took place on the 20 November 2024 virtually, technically hosted by SMIIC General Secretariat. 21 experts participated in the training.

The training was hosted by NMI: SASO NMCC

General Description: The training covers information on the multipoint calibration of pHmeters
and Sources of uncertainty.

Objective, expected outcome: To provide knowledge to participants of the importance of pH
measurements and how to calibrate the devices used for this purpose.

Who should attend: Staff working in metrology laboratories at the level of NMIs and testing laboratories.
