OKO-NDT Eddy Current Pencil Probe, Straight Shaft Surface Probe (Single / Single Shielded) - 500 kHz, Ø 4.5 mm Tip, 115 mm Length, Microdot Connector, Fe/NFe Compatibility

This OKO-NDT Eddy Current Pencil Probe is a precision-engineered, straight-shaft surface probe (likely part of OKO-NDT's SU series) designed for highly accurate surface and near-surface flaw detection in a broad range of conductive materials. Its specific configuration makes it an invaluable tool for manual eddy current inspections in demanding industrial environments, combining sensitivity with ergonomic handling.

Key Features & Benefits:

• Pencil Probe / Straight Shaft Design: The slender, ergonomic design with a straight shaft allows for precise manual scanning. It is particularly effective for inspecting hard-to-reach areas, intricate geometries, weld toes, fastener holes (around the edges), and other areas where traditional bulkier probes cannot access effectively.

• Optimal 500 kHz Centre Frequency: This mid-range frequency offers an excellent balance for eddy current testing:

  • It provides good penetration depth for detecting near-surface defects in various materials.

  • It's well-suited for inspecting both highly conductive non-ferrous materials (like aluminum) and ferrous materials (like steel), with good signal-to-noise characteristics.

  • Offers good phase discrimination, aiding in distinguishing between different types of indications (e.g., flaws vs. lift-off variations).

• Small Tip Diameter (Ø 4.5 mm): The compact sensing tip provides high resolution, enabling the detection and characterization of very fine, surface-breaking cracks, pits, and discontinuities. This small footprint is critical for inspecting small components or areas with tight tolerances.

• Single Coil, Single Shielded Configuration:

  • Single Coil (Absolute): Provides a general response to variations in material properties, including cracks, material sorting, and heat treatment.

  • Single Shielded: The shielding concentrates the probe's magnetic field, improving focus and minimizing interference from edges or nearby structures. This results in cleaner signals and better defect localization, enhancing inspection accuracy.

    
    

• Versatile Material Compatibility (Fe/NFe): This probe is designed for use on both ferrous (Fe) materials like steels and cast iron, and non-ferrous (NFe) materials such as aluminum, titanium, copper alloys, and stainless steels, making it highly adaptable for diverse applications.

• Durable & Ergonomic Construction: Built by OKO-NDT (OKOndt GROUP), the probe features a robust body designed to withstand the rigors of continuous use in industrial settings, while maintaining a comfortable grip for the operator.

• Standard Microdot Connector: Equipped with a widely used Microdot connector, ensuring broad compatibility with most conventional eddy current flaw detectors from various manufacturers.
