CraftsmanCapitol™ Premium Coating Thickness Digital Gauge

  • Saving time and no more hassle with your project
  • 100% Money-Back Guarantee

This digital coating tester is designed to not-destructively measure the thickness of non-magnetic coatings (paint, film, enamel, plastic, epoxy etc.) on iron, steel or aluminum.

Product features:

  • Principle and Application:The coating thickness gauge uses electromagnetic induction principle and magnetic induction EDD current. It can quickly, non-destructively and accurately measure the thickness of non-metallic coatings (such as paints, films, etc.) on metal substrates and display the results on the LCD display. Widely used in manufacturing, automotive, metal processing, chemical industry, commodity inspection, and other industries
  • High precision:High-precision integrated probe, more accurate measurement; three measurement modes: SNG mode measures and gets a result once. CTN mode continues to measure and display dynamic results. DIF mode will calculate the difference between the most recent two; three calibration functions: Zero-point, 2-point and basic. The pedestal has been calibrated. You can also recalibrate the device pedestal on different materials using a given set of 6 calibration films
  • Humanized design:GM200A coating thickness gauge is very small and portable, even in the pocket can easily carry. Anti-slip fingering groove makes it achieve single-handed operation, measurement, and view and makes the operation simpler. Key touch: high-quality matte plastic, feel comfortable
  • Easy to use:Digital LCD display, ultra-clear screen display, with backlight, can still be used in very dark places; battery-powered: use 2 7 batteries, long-lasting. Installation is easy and quick. A battery level indicator lets you know the battery usage; metric and imperial units can be converted
  • Long-term durability: Long-term durability: The car mode/user mode is a two-in-one, free choice. The automatic shutdown feature saves power and extends use time. Suitable for measuring iron, aluminum and zinc coatings. Heavy-duty PC case ensures long-term use of the meter

The Screen Display:
  • If the display shows"--", it means that the tester does not detect any iron, steel or aluminum substrate.
  • If the display shows"OL", it means that the coating thickness exceeds the tester's measuring range.
  • If the display shows"- 0", it means that the probe has wear or the substrate under the coatings may be another kind of metal other than iron, steel or aluminum.

How To Use:

  1. Hold the tester and make sure that it is at least 20cm away from the object to be tested and other objects. Then press the "TEST" button to turn on the tester."--"appear on the display and flashed, meanwhile the unit "mm"appear.
  2. Press the "UNIT" button to select desired unit - mm or mil.
  3. Place the tester's probe perpendicularly on the surface to be tested, the display will show the coating thickness.
  4. When you make a measurement, the reading will remain on the display if you move quickly the tester away from the surface under test. And you can press the "TEST" button to delete this reading, the display will show "--"
  5. If you do not press any button and the tester does not detect the presence of steel, iron or aluminum for about 30 seconds, the tester will turn off automatically.
  6. If you want to turn off the tester manually, press and hold down the "TEST" button for more than about 1 second.
