CRACK DEPTH METER ET-28A high-precision, hand-held instrument explicitly designed for measuring the depth of cracks on various metals and alloys, including stainless steel and duralumin, which have been previously detected by other methods. Non-destructive measurement of crack depths in metals and alloys ■ Operates on the principle of AC electro-potential measurement, providing prompt and precise depth testing compared to traditional methods. It works most efficiently in combination with other crack-revealing methods, such as magnetic particle, capillary, or eddy-current testing. ■ Suitable for measurement on both ferromagnetic and non-ferromagnetic materials (e.g., stainless steel, aluminum alloys). ■ Wide measuring range from 0.2 to 100.0 mm. ■ Minimal influence of material electromagnetic properties on measurement results. ■ Equipped with various probe designs for inspecting products of irregular shapes. ■ Mobile spring-loaded contact electrodes on the probe enable measurements on curved surfaces.

■ Stages of crack depth measuring • Shafts, rolls, rolling mills, construction components, machines, and mechanisms • Pipes, tubes, oil-and-gas pipelines • Pressure vessels • Energy industry devices • Setting of the "0" - measure on an undamaged area of the object. • Measuring of crack depth - position the contact electrodes on opposite sides of the crack, and the depth measurement in mm will be displayed on the screen. Standard probe "1x4". Included with the device. *Available for separate order. Special probe "2x2". Special probe "3x1". For hard-to-reach areas (e.g., fillets)*. For cracks deeper...
