NDV Ultrasonic

As specialist in High-frequency Ultrasonic in Electronics I have always looked for ways to make life more pleasant through electronics. After many repairs to radios, videos and TVs, I started my own company in security in 1987, which was not evident at that time. Now there is a lot of equipment available, but when I started we made our power stations ourselves, because it was simply not available at a decent selling price, but you learn a lot that way. !
