TEQTO → Ferrite Meter and Crack Depth Meter

Ferrite Meter

Our ferrite meters are versatile instruments designed for precise measurement of ferrite content in metal welds, rust-inhibiting coatings, and the base metals of austenitic and austenitic-ferritic stainless steels. These tools provide comprehensive analysis with percentage (%) and ferritic number (FN) scales, ensuring accurate assessments across all measurement ranges.

Ideal for use in laboratory and workshop settings, they are essential for quality control in industries such as nuclear and chemical engineering, shipbuilding, and more. A wide range of transducers is available to accommodate various applications, making our ferrite meters a reliable choice for ensuring the integrity of stainless steel weldings and other critical components.

ET-28 – Crack Depth Meter

ET-28 – Crack depth meter

A 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.

The crack depth meter 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.

Application

  • Shafts, rolls, rolling mills, construction components, machines, and mechanisms
  • Pipes, tubes, oil-and-gas pipelines
  • Pressure vessels
  • Energy industry devices
