General

The ELOTEST PL600 is a digital eddy current test instrument which leaves no wish unfulfilled. A flexible software system
allows components to be inserted which are customised for each application, so that the operation can be carried out
quickly and reliably. A licensing system allows you to match the performance of the device to the task and makes it a safe
investment at an affordable entry price. A sound concept for replacement parts and service reduces operating and maintenance costs and enables maximum availability.
