Cooling Hands For Demonstration

A customer produces traveling science museum exhibits. They are designing an exhibit for children to demonstrate an infrared camera. They want to find a way to cool their hands, then view them through the infrared camera, to see how the display changes as their hands change temperature. A Model 3225 Vortex Tube with Model 3901 Cold Muffler provided sufficient air volume to quickly cool the hands down to a temperature that would provide clear indication of temperature change when viewed through the infrared camera.
