Special test block KO28-2 for crack measurement is designed to test the operability of the Crack depth meter ET-28 electro potential.
5 cracks of different depths were simulated on the KO28-2 sample: 2, 5, 10, 20, 30 mm.
The sample is made of structural carbon steel.
Before each use of the device for measuring the depth of cracks on the product, it is necessary to check its operation on a control sample.
