Product Overview
The CTG-600F190 coating thickness gauge is a precision measuring instrument based on the magnetic principle, specifically designed for measuring the thickness of non-magnetic coatings on magnetic substrates (such as steel and iron), including paint layers, powder coatings, plastics, porcelain, chromium, copper, zinc, and more. It enables fast, non-destructive, and precise measurements, making it suitable for various environments such as laboratories and engineering sites. Its F190 long rod probe is particularly well-suited for measuring coating thickness in internal holes or narrow spaces.
This instrument features a backlight, large-screen digital display, single-point and multi-point calibration functions, and is characterized by resistance to high and low temperatures, impact resistance, probe durability (over 500,000 cycles), excellent testing stability, and high speed. Its technical parameters comply with both national and international standards.

Working principle
The CTG-600F190 coating thickness gauge operates based on the magnetic principle. It accurately calculates the thickness of non-magnetic coatings (such as paint or plastic) by measuring changes in magnetic flux or magnetic reluctance between a magnetic substrate (like steel) and the non-magnetic coating. The instrument’s probe generates a magnetic field, and when it approaches the test object, the characteristics of the magnetic field change depending on the coating thickness. The internal circuitry of the instrument detects this change and converts it into a thickness value for display.

Operating Procedures
1. Power on the device and ensure it has sufficient battery.
2. Select the appropriate measurement mode (single-point or continuous) based on measurement needs.
3. Before measuring, calibrate using a standard block or a sample of known thickness (zero-point, single-point, or five-point calibration options are available).
4. Place the F190 long rod probe vertically and steadily on the surface of the coating to be measured.
5. Read the thickness measurement value displayed on the screen.
6. Upper and lower alarm limits can be set; if the measurement result exceeds the range, the device will provide a color-coded alert.
7. Measurement data can be automatically stored and exported via USB connection to a computer for report generation.
Precautions
• Always calibrate the instrument on an uncoated area with the same substrate and curvature before measurement to ensure accuracy.
• Ensure that the probe's measuring surface is perpendicular to and in close contact with the coated surface being measured.
• Avoid using the instrument in environments with strong magnetic fields or severe vibrations.
• The instrument and probe should be protected from strong impacts or drops.
• Regularly clean the measuring surface of the probe to prevent oil, dust, or other contaminants from affecting measurement accuracy.
• For workpieces with special shapes (such as small cylinders), it is recommended to use a suitable probe (e.g., a large V-shaped probe) to ensure measurement stability.
• Remove the batteries if the instrument will not be used for an extended period.
