The Story
Coating Thickness Gauge – QualiCTG-III
Coating Thickness Gauge series can non-destructively measure the thickness of non-conductive coatings on metal surfaces and non-ferromagnetic metal coatings on ferromagnetic metals (e.g. iron, nickel, cobalt, etc.), including measuring the thickness of iron, stainless steel surface paint or galvanized layer, measuring the thickness of aluminum, copper surface paint or plastic film.
QualiCTG-III Coating Thickness Gauge is equipped with external probe for easy replacement and it is suitable to work in narrower spaces. With the magnetic induction and eddy current effect integrated probe, the maximum range is 5000μm and the highest resolution is 0.1μm.
QualiCTG-III is highly anti-interferent and can work in complex electromagnetic fields. During measurement, the user needs to quickly place the end of probe to the surface of the object being measured, during the process the instrument can automatically distinguish the properties of the substrate and measure the thickness of the coating (plating) layer. The measurement results can be sent to the APP in real time by Bluetooth. Besides, with large memory capacity, the gauge records data automatically. These test results can be sent to computer by USB.
QualiCTG-III has a capable data processing ability, can display a variety of statistics map and data, and can indicate and alert the over-limit situations. The instrument integrates AI technology and adds the functions of environment self-adaptation and self-protection. The instrument is with a simple standardized menu interface on the large color screen. The realization of many advanced technology and schemes has greatly enhanced the user’s sense of human-computer interaction experience.
