A love tester machine (also called love meter or love teller) is a type of amusement personality tester machine, which upon receiving credit tries to rate the subject's sex appeal, love abilities or romantic feelings for someone. Many love testers measure the moisture on the skin surface of the subject's hands by electrically testing the skin conductance and rates accordingly. Others measure the temperature of the skin. However, some machines just use a random generator. Love meters could be found in penny arcades, and can be seen in modern video arcades, amusement parks, in bars and restaurants. Such vending machines are for amusement purposes only and do not actually give a real result.[1] Nintendo, before entering the video game industry, released their own handheld love tester.
