The Raytek MiniTemp is a non-contact temperature reader. Point it at something and it will tell you how hot or cold it is. I’m sure this could be a really useful tool, but darned if I can work out how. $99.00.
‘Simply squeeze the trigger and an instant reading, based on infra-red emissions, appears on the backlit display. With a temperature range of 0 to 500 degrees Fahrenheit, you can check the temperature of that overclocked chip you have running in your case. Also check your oven, refrigerator, heater, AC, fish tank, wine cellar, and so on.’
