Kowolux X4/X4eco

The Kowolux X4 and X4eco High Intensity X-Ray Film Viewers are designed for high end NDT x-ray film evaluation. These viewers feature the latest POWER-LED Technology, providing magnificent white light over the whole control range. The higher contrast helps inspection operators to find defects and discontinuities easily. Even with very dark films, the High luminance makes it possible to view without destroying them.

Due to the higher efficiency of LED’s, heat generation and power consumption is reduced by 80% when compared to conventional viewers with halogen lamps. With a life span of up to 40,000 hours, frequent bulb replacement is a thing of the past, making it a cost effective choice.

Constructed with an economically designed housing made of durable stainless steel, and a cooling fan that reduces irritating noise. A large variety of accessories make handling films very easy.
