Telethermographic System


IRBC37 Blackbody Calibration device has been designed to increase the accuracy of thermographic systems. It has excellent temperature uniformity across the heated surface 0.014°C, high emissivity >98%, the temperature stability of 0.005°C, and high accuracy of ±0.07°C. IRBC37 Blackbody Calibration device has a stabilization time of fewer than 10 minutes with a user-adjustable temperature range of 30°C to 45°C.

Fever is a common symptom of COVID-19, typically appearing 2-14 days after exposure. Telethermographic systems can determine surface skin temperature, which is then used to estimate the temperature at a reference body site. The advantage of using telethermographic systems for initial temperature assessment is the potential use in high throughput areas (e.g., airports, bus/ rail stations, businesses, schools, government offices, factories) and in settings where other temperature assessment products may be in short supply.

Its main features, including non-contact rapid screening of body temperature, long-distance, large area detection, intelligent alarm, fast response, high-temperature measurement accuracy, infrared and visible image overlay temperature measurement analysis.

A thermal camera in combination with intelligent backend software helps detect persons with higher than normal temperatures entering a given area. The system accuracy is enhanced by a blackbody calibrator as it maintains a steady temperature over a surface that the thermal camera uses as an accurate temperature reference. Hence the blackbody calibrator is considered a critical component in the entire system.

The purpose of the blackbody calibrator is to provide a surface with a uniform heat distribution with an emissivity close to 1, to be used as a reference for thermal cameras to accurately deduce the temperature of persons in a defined area. Hence the accuracy, even heat distribution and stability of the blackbody calibrator are considered as critical features of the entire system.
