PYXSEE-Pro: Non-Destructive Testing (NDT)
At Kwan-tek, we believe that inspecting the integrity of structures and materials should never mean compromising them. That’s why we are redefining non-destructive testing (NDT) with state-of-the-art quantum sensing. Our innovative quantum sensor technology based on NV-diamond magnetometry opens new pathways to detect flaws, cracks, monitor critical assets, and secure your operations — all without damage and with minimal disruption.
Quantum Technology for Advanced Non-Destructive Testing
Kwan-tek’s quantum NDT technology uses nitrogen-vacancy (NV) centers in diamond to measure subtle magnetic field variations associated with material defects, structural changes and residual stresses.
Combined with magnetic flux leakage or eddy-current techniques, our sensors support high-resolution inspection of metallic components, helping identify and characterize anomalies that can be challenging to assess with conventional methods.
How NV Diamond Sensors Detect Material Defects
NV diamond sensors detect magnetic field variations through the quantum properties of nitrogen-vacancy centers in diamond. Using optical excitation and microwave control, they convert magnetic signals into measurable responses.
This approach enables high-resolution magnetic measurements to investigate microcracks, material transformations and stress-related anomalies, depending on the material and inspection configuration.

Quantum diamond sensors measure tiny changes at the microscale, ensuring that smallest defects do not escape detection.
Our solution provides quantitative, offering richer insights for better maintenance decisions.
The compact design of our NV magnetometer probes allows them to fit easily into robotic arms, handheld inspection devices, or fully automated lines.
Diamonds don’t just enable quantum sensing, they make our sensors exceptionally resistant to heat, pressure, and wear. This ensures stable measurements year-round.
Early detection means fewer unexpected failures, optimized maintenance schedules, and better resource allocation, translating to significant savings over time.
Our sensors can be deployed remotely, even in difficult or hazardous locations. Inspections can be performed safely without exposing operators to risks.
Fields of application
Kwan-tek’s quantum NDT solutions are trusted in sectors where failure is not an option:
- Aerospace & Defence — Inspect fuselages, wings, turbine blades to detect hidden fatigue before it becomes a threat.
- Energy, Oil & Gas, Nuclear — Monitor pipelines, pressure vessels, and critical infrastructure continuously, even in extreme temperatures or high-radiation zones.
- Hydrogen & Emerging Clean Tech — Validate the integrity of tanks and high-pressure systems designed for next-generation fuels.
- Metallurgy & Advanced Manufacturing — Inspect welds, joints, and metal structures without halting production — ensuring the highest safety and compliance standards.
Our Low-Field NV Magnetometer: a closer look
Compact yet powerful, the Kwan-tek Low-Field NV Magnetometer uses a fiber-optic probe to measure the magnetic field generated by imperfections or stress concentrations within a material. Its small footprint and fast measurement capability make it ideal for integration into inline inspection stations or mobile inspection kits.
Key benefits include:
- Surface and subsurface defect detection up to 10 mm deep in metals (depending on material properties).
- Adaptability to complex geometries, remote areas, or harsh conditions.
- Optical readout that eliminates interference from temperature fluctuations or mechanical vibrations.
Kwan-tek has demonstrated the potential of NV diamond magnetometry for several industrial inspection challenges:
- Grinding Burn Detection: Detection of grinding burns in steel components, including weak thermal damage.
- Microcrack Detection: Detection of an artificial crack approximately 100 µm wide and 300 µm deep in 304L stainless steel using eddy-current excitation.
- Material Characterization: Detection of deformation-induced martensitic transformations in austenitic stainless steel.
