Klas-E

	Klas®-E
	Auricular Laser Acupuncture Unit Red Laser 660nm/20~50mW

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 with automatic power control (APC) 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)
		over-temperature
		under-voltage
		soft-start
		short-term reverse battery connection

Convenient		Shockproof with all stainless steel robust construction and the compact assembly can be put in the aluminum case for fully portable handling.
		60 °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 practitioner.
		Powered by three alkaline AAA batteries which provide Klas-E50 approximately 9 hours continuous operation.
