3/3/2026

Abstract Forehead Infrared Radiation Thermometers (FIRTs) are widely employed in healthcare settings and access control due to their practicality. However, concerns persist regarding their metrological reliability, particularly in clinical applications. These devices operate in two modes: object and adjusted (body temperature). However, current evaluation methodologies lack standardised procedure…
