To this end, advanced studies candidates in the Graduate Engineering Department of Texas A&M University have developed an easily used fully portable Beer Temperature Tester which easily indicates whether the beverage is acceptably chilled or not. To test the beer, simply insert the tester into the glass.



After the tester has been immersed for a period of no less than fifteen seconds, remove both probes and observe the indication.



The beer on the left is the correct temperature.
