Eddy Current Technology invented the world’s first practical, simultaneous injection, multi-frequency eddy current instrument in 1979 and later patented it. As a result, Eddy Current Technology Incorporated has been building simultaneous injection multi-frequency eddy current instruments for over 30 years, longer than any other company. It is apparent that all of our competitors that offer similar equipment are using our basic design. We use a much higher resolution screen than competitors do; as a result, we can display not 4, but 12 impedance plane screens each with an 8-bit (256 x 256 pixel) resolution. Thus, all 8 frequency channels, plus 4 mixers, are visible on the screen simultaneously.
In the early 1980s, we developed the first eddy current instrumentation and probes that was capable of detecting circumferential cracks at the tube sheet expansion transition zone in heat exchangers. These probes have no moving parts, so the inspection speed and probe life are both very high.
Eddy Current Technology Incorporated developed Near Field™ testing of ferrous tubes in heat exchangers decades ago, but ours is superior to Near Field™ testing which is available from only one competitor. That competitor’s technology is not capable of detecting outside defects.
In addition to having a Near Field™ capability and a Remote Field capability, we also offer Remote Field and Near Field™ simultaneously for testing of ferrous tubes. No other manufacturer has been able to develop a similar product as yet.
Our eddy current instruments have always been the smallest and lightest available for any given capability level. At only 5 pounds, the new 4 frequency, 8 channel ect 48 μ Dock is no exception.
