CN-37: Thermal cameras’ reference source for real-time fever detection

With the Covid-19 pandemic spreading around the globe, EOI, an HGH company, developed a new Blackbody technology to answer IR thermography camera manufacturers' increasing needs. 

► Certificate of calibration at human fever temperature

► Compact and robust design

► High stability of regulation

► IEC 80601-2-59 standard compliant

Main application of thermal imagers consists in screening for elevated body temperature. The detection of fever, which is a key symptom of Coronavirus, provides a datapoint that can help airports, hospitals, factories, hotels, or any high traffic places to prevent the spread of the disease.


Thermal cameras can detect sick people in a crowd, based on their body temperature

In order to avoid any drift or error of detection, a reference temperature point such as the new CN-37 is required in the field of view of the camera. The CN-37 Blackbody is compatible with all thermography cameras on the market.

An International Primary Standards traceable certificate of calibration at human fever temperature is provided.
