Eliminate uncertainty about image quality and regulatory compliance in NDT. IQI (Image Quality Indicators), or Penetrameters, are precision-machined reference tools used to objectively verify the quality and sensitivity of your radiographic technique. They provide a measurable gauge of detail resolution. Available in various types (wire, step-wedge, and plaque) and material groups (e.g., Fe, Al, Ti), they ensure strict compliance with major NDT standards including ASTM, EN, and ISO specifications.
