Crack depth meter 281M electro potential

Crack depth meter 281M – high-precision instrument for measuring the depth of cracks exposed on various metals and alloys (incl. stainless steel, duraluminum), previously detected by other methods.

The operating principle of the Crack Depth Meter – AC electro potential measuring that provides prompt and precise depth test (in comparison to traditional methods).

The device is the most efficient in combination with other crack-revealing methods: magnetic particle, capillary or eddy-current.

Exploitation advantages

Stages of crack depth measuring

1. Setting of the “0” – measuring on flawless location of the object.
2. Measuring of crack depth – contact electrodes are located on the opposite sides of the crack, measurement result in mm is shown on the screen.

Requirements for control objects

• Surface roughness – below or equal to 40 Rz (10 Ra)
• Stable electric contact with the sensor electrodes
