TealDHMO uses the IR port of your handheld to perform a test for the presence of DHMO (Dihydrogen Monoxide), a chemical which has been found to be harmful when inhaled or subjected to prolonged exposure. The technology used in TealDHMO is experimental, so results returned by it are preliminary and should not be considered conclusive. Users, particularly those who get positive test results, should carefully read more about DHMO online.
