Advanced handheld eddy current testing

Introducing MIZ-21C, the most advanced handheld instrument with surface array capabilities. The truly affordable MIZ-21C is ideal for aerospaceoil & gasmanufacturing and power generation applications. Its ergonomic design, long battery life and intuitive touchscreen enable the user to inspect more areas faster than ever without fatigue.

With new features that include a fully sealed unit, increased operating temperature range, up to 10 hours of battery life, increased internal storage capacity and more, MIZ-21C maximizes inspection efficiency and value.

Save time and money

MIZ-21C is a fast, highly portable and cost-effective replacement for Liquid Penetrant Testing (PT) and Magnetic Particle Testing (MT) inspections. The surface array option can reduce inspection time by up to 95% versus pencil probes.

MIZ-21C’s intuitive touchscreen and simple, yet powerful embedded software gets users inspecting in no time, offering quick set-up and hassle-free operation.

Inspect more areas

The MIZ-21C is designed for user comfort. It can be held for twice as long as other Eddy Current portable devices. The small form factor enables users to inspect hard-to-reach areas and components that other instruments can’t. MIZ-21C brings the power of surface array to places it has never been before.

Improve flaw detection

MIZ-21C features an industry-leading signal quality providing up to 25% better flaw detection capability. When coupled with surface array, users can be confident that MIZ-21C will deliver the most thorough inspection in its class.

Designed for a wide range of applications

MIZ-21C delivers an inspection advantage across numerous inspection applications including:

Detecting Cracks Near Fastener Holes. Pencil probes are ideal for detecting small cracks in close proximity to fastener holes. The inspector uses a known crack or notch standard to set up the MIZ-21C signal display. Then, while scanning the test piece, the inspector can estimate the depth and length of surface cracks by comparing the phase and amplitude of the generated eddy current signal to the standard’s signal.

Multi-Layer Corrosion Inspection. Identifying corrosion is one of the most critical and complex aspects of airframe inspections. Changes in skin thickness as well as varying multi-layer structures usually make it difficult to recognize signals. The MIZ-21C has the power to penetrate thick sections. Exceptional signal-to-noise ratio helps inspectors distinguish even a small loss of material. Dual-frequency with mixing nearly eliminates the unwanted signals caused by varying air gaps between layers that can “mask” the signal of interest.

Conductivity and Coating Thickness Measurement. Use digital conductivity measurements (resistivity) to characterize/sort materials. Directly measure the conductivity of metals and alloys, such as aluminum structures, using dedicated conductivity probes that have a broad operating frequency range. Or measure a nonconductive coating such as paint. The MIZ-21C offers a wide measurement range for both conductivity and thickness.

Three models to meet your needs and budget

  • MIZ-21C-SF: Single frequency, conductivity
  • MIZ-21C: Dual Frequency, Conductivity, Rotating Scanner
  • MIZ-21C-Array: Dual Frequency, Conductivity, Rotating Scanner, ECA

For inspection applications that demand highly portable eddy current or eddy current array capabilities, the MIZ-21C is the only choice.

Cost-effective, highly portable surface array solution

When the MIZ-21C is used along with Zetec Surf-X Array Probes, it’s the most cost-effective, portable surface array solution in the market. This solution delivers significant inspection advantages over Liquid Penetrant Testing (PT) and Magnetic Particle Testing (MT).

ZM-5 Rotating Scanner for small diameter holes

Zetec’s ZM-5 High-Speed Scanner is a convenient handheld tool designed for rapid and thorough inspection of small diameter holes, such as bolt hole and fastener holes. With an ergonomic design, the ZM-5 enables inspection of the hardest to reach areas. A rotating transformer couples the eddy current signals for an improved operating life over conventional slip rings. The ZM-5 uses a quick-disconnect cable design for easy replacement. Thanks to the higher signal to noise ratio, the MIZ-21C and ZM-5 are an ideal bolt hole solution providing a better probability of detection for multi-layer bolt hole inspections as shown in the image. Through adapters, the MIZ-21C can drive other manufacturers’ rotating scanners.

Surf-X Array Probes for faster flaw detection

Introducing the Zetec Surf-X line of array probes. Featuring a unique flexible circuit design and proprietary X-Probe technology, Surf-X array probes can lower total cost of ownership while providing excellent data quality as well as faster, safer inspections when compared with other inspection methods.

Inspecting Corrosion or Cracking in Pipes, Pressure Vessels, or Tanks. Surf-X Flex Probes can conform to gradual changes in the geometry of pipes, pressure vessels, or tanks to detect surface and sub-surface flaws in a variety of materials including aluminum and stainless steel. Corrosion is a common flaw in non-pressurized components, while stress corrosion cracking is common in components subjected to sustained tensile stress in a corrosive environment. The Surf-X array probe can easily detect the locations of both types of defects using the high precision embedded encoder to track position.

Assessing and Sizing Cracks in Raised Welds and Friction Stir Welds. Surf-X Weld Probes can conform to geometry changes associated with raised welds to simultaneously inspect for axial and transverse cracking in the weld cap, toe, and heat-affected zones. Surf-X array probes use position indicators on the probe to help with alignment to ensure the entire area of interest is inspected. The flexible nature of the Surf-X array probe allows for the inspection of flat surfaces including friction stir welds. The long-life wear surface has been tested to 10,000 ft.
