Available in JCZ-5, JCZ-10, JCZ-20, JCZ-30 and JCZ-50 models.
Designed for residual magnetism inspection of ferromagnetic materials and components, demagnetization checks after magnetic-particle testing, and magnetization measurements during processing.
The JCZ Magnetic Field Intensity Meter is a portable instrument for measuring residual magnetic fields on the surfaces of ferromagnetic materials and components. The magnetic probe attachment can be placed close to the workpiece surface. Move the instrument across the test area and read the residual magnetic field from the indication.
It is suitable for machining, magnetic-particle inspection, demagnetization and quality-control applications. After magnetic-particle testing, the instrument can be used to check residual magnetism and help determine whether demagnetization meets process requirements.
Available in JCZ-5, JCZ-10, JCZ-20, JCZ-30 and JCZ-50 models.
All models have a nominal accuracy of +/-10% and are suitable for field residual-magnetism checks.
The compact circular design makes it convenient to move the meter close to the workpiece surface.
| Model | Measurement Range | Accuracy | Dimensions | Operating Environment |
|---|---|---|---|---|
| JCZ-5 | 0 to 5 x 10-4 T | +/-10% | 60 mm x 23 mm | -10 to 50 degrees C Relative humidity ≤80% |
| JCZ-10 | 0 to 10 x 10-4 T | +/-10% | 60 mm x 23 mm | |
| JCZ-20 | 0 to 20 x 10-4 T | +/-10% | 60 mm x 23 mm | |
| JCZ-30 | 0 to 30 x 10-4 T | +/-10% | 60 mm x 23 mm | |
| JCZ-50 | 0 to 50 x 10-4 T | +/-10% | 60 mm x 23 mm |
Conversion: 1 gauss (G) = 1 x 10-4 tesla (T).
Suitable for workpieces with low residual magnetism where small magnetic-field changes need to be observed.
Suitable for routine inspection of ferromagnetic parts, machined components and demagnetized workpieces.
Suitable for workpieces with a larger residual-magnetism range and applications requiring a higher measurement limit.
It is mainly used to measure residual magnetic fields on ferromagnetic materials and components, including residual magnetism after demagnetization.
The measurement range is different. The upper limit increases progressively from JCZ-5 to JCZ-50.
The magnetic field may not be uniform across the workpiece surface. Moving the meter helps locate the maximum residual field in the test area.
It is not recommended. A nearby strong magnetic field can increase measurement error, so keep the instrument away from magnets, magnetizing equipment and high-current devices.
Portable residual-magnetism meter for ferromagnetic materials, components and demagnetized workpieces, with five measurement ranges.
| Model | Measurement Range | Accuracy | Dimensions | Price (USD) |
