Eureka3

Powerful Adaptive Filtering

The Eureka3+ variant incorporates an advanced Adaptive Filter. This operates live, selecting the correct frequency ranges and suppressing background noise for optimum correlation. This filter enables the Eureka3+ to locate difficult leaks missed by correlators using conventional filters. The Eureka3+ also features post-processing, such that results can be re-analysed on and off site.

16-bit online and offline correlation

The Eureka3/3+ system pinpoints leaks accurately so that fewer holes need to be dug, minimising disruption to the network. The system can correlate noise signals and find leaks even before pipe details have been entered.

Rugged, portable and easy to use

Built to a high spec the Eureka3/3+ can be operated for long periods between servicing. Its portability means many leaks can be found per man per hour. With its touch screen processor PrimeTouch it correlates noise signals from its two loggers and confirms the leak with its ground microphone. The battery can be charged in the system case from the mains or a van.
