Product Overview
The Yibai CTG-600 Large V Coating Thickness Gauge is a high-precision, multifunctional instrument for measuring coating thickness. It features a modular design with detachable and interchangeable probes, and includes a large V-shaped probe specifically designed for measuring curved surfaces such as cylinders to ensure measurement stability.
Product Features
1. High-precision measurement across the entire linear range.
2. Dual-use for iron and aluminum with automatic identification (FN type).
3. Split design with detachable and interchangeable probes.
4. Accurately measures coatings and platings up to 10 micrometers thick.
5. High-wear-resistant carbide probe with a lifespan exceeding 500,000 uses.
6. Features zero calibration, single-point calibration, five-point calibration, and factory reset functions.
7. Upper and lower limit alarm settings with color-coded indicators.
8. Statistical functions display average, maximum, minimum, test count, and standard deviation.
9. Supports both single-point measurement and continuous measurement modes.
10. Zinc coating weight version (CTG-600Z) simultaneously displays zinc coating weight and thickness.
11. For measuring cylinders, a large V-shaped probe can be selected to ensure measurement stability.
12. Stores up to 1,600 measurement data points (16 groups, 100 per group).
13. Connects to USB computer software to generate measurement reports for easy data management.
Working principle
The instrument operates based on the principles of electromagnetic induction and eddy current effects. For non-magnetic coatings on ferromagnetic substrates, the electromagnetic induction method is used for measurement; for insulating coatings on non-ferromagnetic metal substrates, the eddy current method is employed. The instrument can automatically identify the substrate material and switch to the corresponding measurement mode.
Operating Steps
1. Select the appropriate probe or instrument mode (such as dual-use for iron and aluminum) based on the substrate material being tested.
2. Perform zero calibration on an uncoated area of the substrate.
3. Use standard calibration pieces for single-point or five-point calibration.
4. Place the probe vertically on the surface of the coating to be measured for testing.
5. Choose between single-point or continuous measurement modes.
6. View, analyze, or export stored measurement data through the instrument.
Precautions
• Always calibrate on the corresponding substrate before measurement.
• Ensure the probe is perpendicular to the coating surface during contact.
• For curved surface measurements, it is recommended to use a dedicated large V-shaped probe to ensure stability and accuracy.
• Avoid using the instrument in environments with strong magnetic or electric fields, as they may interfere with measurement results.
• Keep the probe clean to prevent wear or contamination from affecting measurement accuracy.
• Regularly check the instrument's accuracy using standard calibration pieces and recalibrate when necessary.
