Introducing MIZ-21C, the most advanced handheld instrument with surface array capabilities.
The truly affordable MIZ-21C is ideal for aerospace, oil & gas, manufacturing 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.
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.
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.
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.
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.
For inspection applications that demand highly portable eddy current or eddy current array capabilities, the MIZ-21C is the only choice.
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).
MIZ-21C is an affordable and capable handheld device that can handle inspections
virtually anywhere. With best in class features that not only save time but open the
door to new inspection possibilities.
MIZ-21C offers a range of accessories designed to meet your specific inspection needs.
Removable cover with adjustable hand straps and stand is included with all MIZ-21C
models for added protection, convenience and extended operation.
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.
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.
