The Guyana National Bureau of Standards (GNBS) has announced guidelines for Infrared Temperature Guns that are being used to test body temperature, including that they be tested and calibrated by the agency. The GNBS made the announcement in a July 10, 2020 advisory for stakeholders in all sectors, including health, aviation, education, retail and commercial, manufacturing, forest, tourism and hospitality, mining, energy, agriculture and services. The use of the temperature guns are a growing practice among entities seeking to screen persons for COVID-19.
It recommended calibration by the GNBS, while noting that this is necessary to prevent error in the accuracy in the measurement of temperature. The GNBS, however, said that it has the capacity to calibrate infrared temperature guns with a minimum measuring range of 16.5 cm.
