Low and stable contact resistance

Contact resistance between inner spring type contact probe and target workpiece tends to be unstable, and this fluctuation becomes bigger as number of contacts increase. Sankei's outer spring type contact probe, thanks to its design, continues to provide low and stable data, and is sure to be a reliable partner for precision measurement.
