Mobile phones play a very important role in our life. But this sould be used very carefully since phones generate some harmful raidations like RF (Radio Frequency) . The effect of RF radiation of phones to the human body can be measured by SAR (Specific Absorbtion Rate) . Here comes the use of KARP product for protection from these raidations. SAR is the rate of heat absorbed into the human head while using cell phone. It is the measure of energy absorption by the body tissue from the source(source can be a cell phone) . It is used for ensuring that the device will be safe to use. reduce the risk from the positive ions up to 99.99% with good condition A device with a high level SAR is very dangerous to humans.
