SI Calibration

Having historically been involved in metrology for the past 15 years, the decision was made to pursue ISO17025:2017 accreditation through SANAS, thereby offering our customers peace of mind that calibrations are conducted according to the strictest of standards and that the competence of the laboratory and its staff has been tested and proven satisfactory in providing accurate results to our customers.

The laboratory achieved ISO17025:2017 accreditation in the field of temperature metrology early in 2021, and a copy of our scope of accreditation can be found by clicking on this link.

SI Calibration is committed to continuous improvement and will be pursuing accreditation in additional disciplines as well as expanding on the scope we are currently accredited for, so please watch this space.


We also offer the auxiliary services of validations on boxes, routes, vehicles, transport and others, as well as mapping of warehouses, vehicles, fridges, freezers etc.

Our office is based in Boksburg, Gauteng however we have trained technicians available to service any location in South Africa.

As we are always working on improving our systems and we welcome all feedback, whether it be positive feedback or complaints, positive feedback will be highly appreciated and complaints will be dealt with professionally and timeously, to provide us with any feedback or complaints please click here.
