Specific Absorption Rate

In everyday life, invisible electromagnetic waves are generated when using portable transmission wireless equipment. These electromagnetic waves can be absorbed into a person or animal's body. It ensures stability and accuracy in consideration of domestic and foreign technical standards and laws, and has the ability to conduct tests on foreign standards such as Canada and the U.S.A.
