This special hand-held tool emits infrared light through a focused diode tip, calibrated at precisely 950 nanometers. IR light is used particularly in the Esogetic system for treatment of pain. Note: unlike other less expensive IR tools currently on the market that often use plastic diodes and poorer quality parts, the Perlux IR-950 uses a high-quality glass diode embedded in a special metal socket. This guarantees the “stability” or reliability of the IR frequency in your treatments. Price is $570 plus shipping. Please call for consultation in order to purchase this product.
