The FNIRSI CTG-20 digital coating thickness gauge is a precise and portable tool designed to measure the thickness of coatings such as paint, plating, or powder coatings on metal surfaces. Utilizing a precise internal probe, it automatically detects the substrate type (ferrous or non-ferrous) and measures thickness non-destructively using electromagnetic induction and eddy current principles. Its high speed and accuracy make the CTG-20 an ideal choice for manufacturing, chemical, automotive industries, and car paint inspection.

The FNIRSI CTG-20 coating thickness gauge is an advanced measuring device that uses two main technologies for thickness measurement. Its probe operates dually and intelligently detects whether the substrate is ferrous metal (like steel) or non-ferrous metal (like aluminum). For ferrous substrates, it uses the electromagnetic induction principle, and for non-ferrous substrates, it uses the eddy current effect. This automatic detection eliminates the need for manual settings and significantly speeds up the work. With an accuracy of (±3% 2μm) and a resolution of 0.1μm, this device provides reliable results for industrial and inspection applications.
This digital thickness gauge includes features such as automatic screen rotation, making it easy to read numbers from different angles. The data storage capability allows users to record measurement results for documentation and further analysis. Zero and multi-point calibration options ensure the device maintains accuracy over time. However, to achieve precise results, its limitations must be considered. The device is designed for flat or slightly curved surfaces and may produce errors on highly curved, rough surfaces, or very small areas (less than 20mm diameter). Additionally, strong magnetic fields in the environment can negatively affect its performance.
The FNIRSI CTG-20 thickness gauge offers high value with professional features such as automatic substrate detection, high accuracy, and portable design. It is a cost-effective solution for car paint experts, small industrial workshops, and quality control units needing a precise yet affordable tool. Its rechargeable internal battery and lightweight (83 grams) make it ideal for field inspections and continuous use.

در مشخصات فنی دستگاه به درجه حفاظت (IP Rating) خاصی اشاره نشده است. بنابراین، توصیه میشود از دستگاه در محیطهای مرطوب یا پر از گرد و غبار با احتیاط استفاده شود تا به پراب و قطعات داخلی آن آسیبی نرسد.
خیر، این دستگاه منحصراً برای اندازهگیری ضخامت پوشش روی زیرلایههای فلزی (آهنی و غیرآهنی) طراحی شده است و روی سطوح غیرفلزی مانند پلاستیک، چوب یا شیشه کار نمیکند.
این دستگاه از دو نوع کالیبراسیون پشتیبانی میکند: کالیبراسیون نقطه صفر که برای تنظیم مجدد دستگاه روی یک سطح بدون پوشش استفاده میشود و کالیبراسیون چندنقطهای که با استفاده از فویلهای کالیبراسیون با ضخامت مشخص، دقت دستگاه را در محدودههای مختلف تنظیم میکند.
بله، این یکی از اصلیترین کاربردهای دستگاه CTG-20 است. با اندازهگیری ضخامت رنگ در نقاط مختلف بدنه، میتوان به راحتی قسمتهایی که دارای بتونه یا لایه رنگ اضافی (نشاندهنده تعمیر) هستند را شناسایی کرد.
