IR Thermometers
IR Thermometer Set up
 

 

Code Number: 4A10.80

Demo Title: IR Thermometers

Condition: Excellent

Principle: Infrared Temperature Measurements

Area of Study: Thermodynamics

Equipment: 

FLIR camera, Raytek IR Thermometer, IR Fever ( human ) Thermometer, Infrared Viewer with IR diode illuminating array, Black and White camera.

Procedure:

The FLIR camera is the primary for this demonstration and can show a color scale and associated temperature when scanning.  IR temperatures can also be taken with the Raytek and the standard fever thermometer.  Note that the fever themometer has a very limited temperature range.  

You can "see in the dark" with the black and white camera or the IR viewer when using the IR diode illuminating array as the chip in the camera and the viewer is sensitive in the near IR.
