The eddy current bobbin probes are lightweight, economical, but solidly built probes with the coils protected with a plastic sleeve and stainless steel wear guides at front and rear ends. They are ideal for the inspection of heaters, coolers, and heat exchangers.
The probes listed below are regulary stocked for quick delivery. If the probe you require is not indicated, consider the alternate options with slight diameter and frequency variations, which won't affect the quality of your results.
