Abstract
A black body for calibrating an infrared thermometer includes a cavity and is configured to float stably on a surface of a volume of liquid with the cavity in close thermal contact with the liquid and the opening exposed above the surface.
Claims8
A black body for calibrating an infrared thermometer, comprising:
- a cavity, and
- a support connected to the cavity and providing an opening into the cavity,
- wherein said support and said cavity are structured to define means for causing the black body to float freely and stably on a surface of a volume of liquid with the cavity in close thermal contact with the liquid and the opening accessible from above the surface.
A method of calibrating an infrared thermometer comprising
- floating a black body cavity freely on a surface of a volume of liquid at a known temperature with an opening to the cavity accessible from above the sufrace of the liquid, and using the thermometer to measure the temperature inside the black body cavity via the opening, said temperature being used to calibrate said thermometer.
