Oxide Scale Thickness Gauge

The oxide scale thickness gauge measures the thickness of the oxide layer on metal surfaces using magnetic induction or eddy current principles. The probe contacts the sample, generating signal changes that are converted by the instrument into thickness values. It is used for monitoring the condition of oxide layers on materials such as steel and alloys during production and quality inspection.
Selection
Select magnetic induction type (ferrous) or eddy current type (non-ferrous) based on the substrate of the material being tested. Ensure the instrument's measurement range matches the thickness range of the oxide layer. Choose between portable or benchtop models depending on the field environment. The probe size should be suitable for the shape of the inspection area. Verify the calibration certificate and error range.
