Overview
YT4200-P3 is a split iron-based Coating thickness gauge manufactured by 3nh Company, which can quickly and accurately nondestructive detect various nonmagnetic Coating thicknesses coated on magnetic metal substrates. The instrument meets many international and national standards, with stable performance, accurate measurement and powerful functions. It is the basic equipment of the coating surface preparation industry.
Features
1. It can quickly and accurately test the nonmagnetic Coating thickness on a variety of magnetic metal substrates.
2. Probe and host separation, more adaptability.
3. One-click testing, convenient and fast.
4. Two methods of single point calibrating and multi-point calibrating can be used to accurately calibrate the instrument.
5. Low power consumption and power saving, with low power alarm function.
6. Equipped with a backlit display and a buzzer prompt.
7. Probe with high wear resistance, the service life is not less than 800,000 measurements.
8. Measurement modes available, including single point measurement and continuous measurement.
Principle
The instrument fully complies with the magnetic method test principle stipulated in ISO 2178, GB/T 4956, ASTM B499 and other standards, and determines the Coating thickness by measuring the Magnetic flux change between magnetic metal matrix and nonmagnetic coating.
Applications
Manufacturing, metal processing industry, chemical industry and other surface engineering testing fields. Specifically, it can detect nonmagnetic coatings sprayed on various magnetic substrates (such as steel), such as paints, powder spraying, porcelain coating, chrome plating, copper plating, galvanizing coating, etc.
Standards
ASTM B499、ASTM D1400、ISO 2178、ISO 2360、ISO 2808、GB/T 4956/4957、JB/T 8393
Steps
1. According to the measurement requirements, choose the appropriate calibration method (single point calibrated or multi-point calibrated) to calibrate the instrument.
2. Place the split Probe on the surface of the sample to be tested.
3. Press the one-button test button for measurement.
4. Read the measurement results displayed on the backlit display.
Notice
• Ambient Temperature 0~ 40 ℃, Humidity 10~ 90% RH and no condensation.
• Storage temperature is -10~ 50 ° C.
• When measuring, ensure that the minimum size of the measured area is not less than 10 × 10mm.
• For magnetic substrates, the minimum thickness needs to be 0.2mm.
