Technical Data<br />
General<br />
ELOTEST N300 – The high-performance alternative<br />
to the PC-plug-in card. A MUST for all those who<br />
require the highest eddy curent performance data<br />
and want to work with a PC-interconnection such<br />
as high-resolution crack detection on rail heads. Also<br />
ideally suited for labs, schools, universities and<br />
training facilities.<br />
Small, compact with up to 2 independent test channels<br />
for universal and flexible use.<br />
Independent of the PC-hardware due to the<br />
connection via an RJ45 ethernet interface.<br />
