冠盈科技检漏仪研发制造，专注于开发利用不同领域的技术研究成果转化应用于气密性检测。电火花检漏仪是通过对各种金属包装铁罐容器的导电基体防腐层表面加一定量的脉冲高压，如因防腐层过薄，漏金属或有漏气针孔，当脉冲高压经过时，就形成气隙击穿而产生火花放电的原理。基于专用检测仪器的高可靠性，集成可编程控制技术的高科技检测系统，开发出全自动化的新型检测仪器设备。可对金属铁罐包装容器的空罐或灌装产品进行有效的气密性检测，适用于厚度检测范围为0.5-10mm的金属包装.

Guanying technology professional leak detector R & D and manufacturing, focus on the development and utilization of different areas of technology achievements transformation is applied to the air tightness detection. Electric spark detector by pulsed high voltage for a variety of metal packaging tin container conductive substrate coating surface with a certain amount of, as a result of coating too thin, leakage of metal or leakage hole, when the high voltage pulse passes, principle of the formation of air gap breakdown and spark discharge. High reliability of the special detecting instrument based on high-tech detection system, integrated programmable control technology, developed a new type of automatic detection equipment. The metal cans packaging containers empty cans or filling product tightness test and effective, suitable for thickness detection range of metal packaging 0.5-10mm.
