The CMA Passive Layer Tester can reliably indicate the passive layer formed on the stainless steel surface within one second. Until now, it had to be assumed that the protective passive layer would form if stainless steel was processed correctly. With this device, this can be clearly proven. A measured value is obtained that also provides information about the quality of the passive layer. Thus, the passivation process can be tested. You will receive the device in a sturdy plastic case with a German description.
