Laser Acupuncture Unit
Red Laser 660nm/50 ~ 100mW
Infrared Laser 90 ~ 110mW

Klas-A is developed from "Laser Biostimulation" theory and "Low Level Laser Therapy (LLLT)" medical approval. This newest and patented device is made using the combination of modern laser technology and advanced integrated-circuit control.

Klas-A is the most scientifically advanced and effective LLLT device, is better than any personal care LLLT device available without a prescription.

Laser acupuncture is proven to be equivalent to metal needle in view of its stimulus effect on the acupoint.
Laser acupuncture continuously and constantly sustains the stimulus potential. While the stimulant effect of the classical metal needle is high at the time of insertion, it starts decreasing rapidly after only a few seconds. The degree of stimulation afforded by laser acupuncture remains constantly high throughout the entire treatment.

Dr. Pekka K. Pöntinen of Scandinavia, the world's leading authority of LLLT, believes that the day will come when most homes will have a flash-light sized, low level laser device, capable of treating a wide range of medical problems from headaches and arthritis to burns and sports injuries.

Klas-A is specially designed and clinically proven for professional and personal at-home laser acupuncture treatments.
