اختبار شرارة utilizes intelligent variable-frequency high-voltage detection technology to identify pinholes, الشقوق, and other defects in non-conductive coatings on conductive substrates such as metals. It is widely used for inspecting the quality of insulating anti-corrosion coatings on storage tanks, valves, pipelines, and other surfaces. The main unit is portable and housed in a durable ABS enclosure, featuring advanced design and reliable performance. هذا spark tester is essential for applications including anti-corrosion engineering, plastic seam testing, concrete coating airtightness inspection, petrochemical pipeline anti-corrosion testing, and enamel production quality control.
