BLD LWD is an elegant high power long wave Diathermy with solid state feature in its most advanced configuration to date. Their unique capacitive field circuitry provides a long wave frequency of 1 MHz that penetrates deep into muscle tissues. This is affected through point electrodes. These devices enable HF energy to be applied selectively deep in the tissues and joints without unnecessarily affecting the surrounding area. The solid state generator ensures a uniform frequency during treatment and longer life for the device. Plus you can work without interference to the other devices.
