The Covid-19 pandemic has brought the measurement of temperature into the daily lives of South African citizens. A non-contact, infrared thermometer is the primary Covid-19 screening intervention, but can the results be trusted? Reliable measurements are of paramount importance, and it is therefore critically important that these instruments are fit for purpose and used correctly, when performing the screening tests.

The National Metrology Institute of South Africa, (NMISA) is contracted by the Department of Trade, Industry and Competition (dtic) to maintain South Africa's National Measurement Standards and ensure they remain internationally equivalent, thereby facilitating accurate temperature screening for Covid-19.

In order to respond to questions and queries related to Covid-19 temperature screening measurements, NMISA has established a team of experts, representing the relevant public entities as well as private calibration laboratories, who have excelled in their different fields and have extensive experience in fields such as measurement, testing and calibration and their role in quality assurance. These experts are ready to review and provide responses to topical questions received, to ensure that businesses have accurate and reliable information conveniently available from a single source.Submit your question to the Team of Experts​​​
