Hello Sameer,
We purchased the Restek leak detector and have found it to be very useful in
finding leaks in our Helium recovery system. The line is long enough so I
can keep the body far enough away from our unshielded 500 without any interference
or draw hazard. It definitely works with in the 5 gauss radius of this magnet.
Not sure if stronger magnets would be an issue, but I think every lab with a
recovery system should have one these to periodically check for leaks.
Perry.
