Stake coupon

The stake witnesses were designed to perform cathodic protection measurements. They are put in place for the time it takes to perform a measurement and then removed. They are not intended to be permanently installed.

They consist of a fixed steel witness calibrated to 1, 5, 10, 25, 50 or 100cm² as well as an IEC 1010 ø4 socket for connection to a multimeter or recorder.

Their high-density polyethylene body gives them great robustness.
