Auricular Laser Acupuncture Unit
Red Laser 660nm/50 ~ 100mW
Infrared Laser 808nm/110mW

Klas-E 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-E 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.

Klas-E is specially designed and clinically proven for professional auricular laser acupuncture treatments.

Effective Constant laser intensity is maintained by:
Specially designed laser beam closely irradiates the acupoint.
Innovative optics design leads to the maximum output laser power. It is recommended to use alcohol for cleaning the optical glass.
Advanced integrated circuit designed by Konftec to maintain the specific power output even the batteries are in low capacity.
Safe Konftec's integrated circuit design with full protection of:
EDS (Electrostatic Discharge)
short-term reverse battery connection
Convenient Shockproof with all stainless steel robust construction and the compact assembly can be put in the pocket or hand bag for fully portable handling.
50 °C high temperature operation durability suitable for use ANYTIME! ANYWHERE!
Easy to Use Vandal resistant stainless steel pushbutton switch for the simplest operation, can easily be used by private individuals for specific treatments as directed by a medical practitioner.
