Emmissity on ir cameras
WebOct 26, 2012 · You can look directly at the water instead of using electrical tape becuase it has a naturally high emissivity The temeprature should read about 0°C or 32°F Meanwhile, set the emissivity in your camera to 1.00 and measure the reflected temperature using your flat aluminum foil surface. WebThe figure above shows a thermal image of an operating Luminus CTM-18 device. The emissivity of the camera is set at 0.9. This roughly corresponds to the emissivity of the soldermask which has an IR camera temperature that agrees with the thermocouple temperature of 71°C. Note how cold the camera thinks the metal surfaces are, ~40°C.
