General Information:
EPCH-2008 Series 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, etc.

Features:

● Beautiful appearance, easy to carry about and grasp, simple and convenient to use.

● Measuring range covers all nonferrous metal materials, 0.51~112%IACS or 0.3~65MS/m.

● Big screen, big character typeface; displaying measured result, working frequency, temperature, temperature coefficient, etc. simultaneously.

● Properly designed with back-light illumination for reading measured data in poor-light environment.

● Special temperature coefficient setting and auto calibrating mode, convenient and reliable for user to operate.

● Excellent design of lift-off compensation and temperature compensation of the instrument to ensure the precision of measurement.

● With interchangeable probes of the instrument, the user oneself is able to change probes provided by our company without matching.

● With built-in data memory, enough to record 4000 groups of measured data and important measuring parameter; to connect to a computer for forming a complete report.

● Two kinds of measuring units (MS/m or %IACS) for convenient selection. It is easy to switch to resistivity value directly on the measurement interface.

● Three kinds of language selection: Japanese and English.

Application Area:
● Conductivity and resistivity measurement of non-ferromagnetic material

● Determining extent of thermal treatment

● Checking thermal damage, material fatigue and crack

● Determining metal purity

● Monitoring of metal homogeneity

● Metal classification

● Monitoring of strength and hardness

● Detecting the density of powder metallurgy parts

The Primary Indexes Comparing of EPCH-2008A/B/C Series Eddy Current Conductivity Meters

The measurement range of model A, B, B1 or C 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. 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 A, A1, B or B1 is the same as foreign same type instrument. 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 too thin workpiece whose thickness is 0.1mm to 0.3mm, so you no longer have to worry about measuring too thin workpieces.

4. Measurement area
The diameter of eddy current conductivity meter’s probe is usually between 13mm and 14mm, but model B 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 have to worry about measuring too small workpieces.

5. Measuring camber and rapid sorting
Model B has unique camber modification technology, with the special camber measurement mode and “∧” shape probe cover, the camber material can be measured stably.
Model B 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
Model B used the advanced technology, 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 500 sets date. It can be set as auto-saving without affecting the operating speed. You no longer have to take notes but easily view the measurements at any time, that also reduce manual error rate. All models except C of EPCH series’ instruments can connect the computer and upload data to the computer to organize and print

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
All 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.
