Infrared Ear Thermometers Black Body Radiation Source System
The traceability of the BL-2050W infrared blackbody standard device for human body temperature measurement primarily relies on the temperature control and uniformity of the constant-temperature bath to achieve an exceptional emissivity index exceeding 0.999 for its blackbody cavity. The system consists of a portable constant-temperature bath cooled by semiconductor thermoelectric modules (for easy transportation), a human ear temperature blackbody cavity, a standard platinum resistance thermometer, and a high-precision digital temperature display. The blackbody cavity can be equipped with a standard bayonet mount, allowing users to select different types of blackbody cavities according to their specific requirements.
