Description
Overview
GAOTek Precise Coating Thickness Gauge offers three different types of thickness gauges which combine the Hall effect and Eddy current principles to measure the thickness of non-ferromagnetic coatings on ferromagnetic metal substrates (iron, cobalt, nickel and gadolinium) and the thickness of non-conductive coatings on non-magnetic metal substrates (copper, aluminum, magnesium, zinc, chromium, etc.). The instrument is widely used in metal processing, coating, hardware, shipbuilding, aerospace and other fields.
Features
- Iron and aluminum dual use. Identify substrate automatically, and fast automatic conversion. (BGD 542/S&BGD 543/S)
- Sensitive response, and the data can be measured in 0.5 seconds.
- With simple design and small size, it is easy to carry and operate.
- Ruby probe has abrasion and corrosion resistance, which ensures long service life and can avoid errors caused by wear.
- Two units of μm/mil can be selected.
- The advanced digital probe is used to keep the zero-position stable for a long time without drifting. The test data is stable after testing the same position multiple times.
- The thickness gauge adopts a unique algorithm to solve the linearity of the instrument and ensure measurement accuracy. It doesn’t need to be calibrated; it only needs zero adjustment.
