Eddy current inspection equipment eddy current testing equipment eddy current testing machine

Products of this series are the first generation of Digital Conductivity Meter designed with eddy phase. These products may be used for distinguishing, grading, and state detecting for non-ferromagnetic metal. These are commonly used in industries of machinery, electric power, aviation, aerospace, nuke, military, etc.

1. APPLICATIONS

The primary indexes comparing of

HEC-103B1 eddy current conductivity meters

1. Measurement range:

The measurement range of model 103A, 103B, 103B1 is large. Besides copper, copper alloy, aluminum and aluminum alloy, the instrument can also measure titanium, titanium alloy and other low conductivity non-ferrous metal. It is real full measuring range instrument. You needn’t separately buy high or low conductivity instrument, but one our instrument is enough.

2. Lift-off compensation

Lift-off compensation is a important parameter of eddy current conductivity meter, which means the instrument’s capacity for overcoming the non-conductive layer (as paint, coating, etc.) above the tested material. Model HEC-103A, 103A1, 103B or 103B1 is the same as foreign same type instrument, and the only instrument whose lift-off compensation is up to 0.5mm. Even if there are coating, paint, or other impurity and rough surface above the tested material, you could get the accurate testing data only if the gap is less than 0.5mm.

3. Working frequency

The currently used working frequencies are 60 KHz and 500 KHz, 60 KHz for aviation industry standard, 500 KHz for detecting sheet metal. Model B is the only instrument, which has a high and a low frequency probes and the high frequency probe is up to 500 KHz. The high frequency probe can be used for super thin workpiece whose thickness is 0.1mm to 0.3mm, so you no longer need to worry about measuring super thin workpieces.

4. Measurement area

The diameter of eddy current conductivity meter’s probe is usually between 13mm and 14mm, but model HEC-103B has a big probe and a small probe whose diameter is 8mm. The probe is used of electromagnetic shielding technology, that the measured material needn’t be more than twice the size of probe. It can measure the small workpiece with the minimum value of 8mm, so you no longer need to worry about measuring small workpieces.

5. Measuring camber and rapid sorting

Model HEC-103B has unique camber modification technology, with the special camber measurement mode and “∧” shape probe cover, the camber material can be measured stably.

Model HEC-103B has continuity measurement function, which can help you sort materials quickly by setting the upper and lower bound warning, in order to maximize efficiency

6. Temperature compensation

The other instruments have only virtual temperature compensation mode, which can measure accurately only when the calibration standard block’ temperature is same as the measured material. Model HEC-103B used the advanced technology from Germany. It is the only instrument which has the real full-automatic temperature compensation. Even if the block’s temperature is different with the material, it could automatically compensate the standard values.

7. Data storage

All models can save 4000 sets date. It can be set as auto-saving without affecting the operating speed. You no longer need to take notes but easily view the measurements at any time, that also reduce manual error rate. 

8. Measurement accuracy

Each model’s indicators and functions are different from the other, but the most critical parameter called measurement accuracy of instrument is uncompromising. All models’ accuracy is up to ±0.5% ~ ±1% as the foreign same type instrument, to ensure the most precise measurements.

9. Measurement parameter

Every models have three kinds of measurement parameters are “MS/m”, “%IACS” and “ῼ • mm²/m”, one keyboard toggle without manual handling, be wonderfully easy to use.
