探头根据DIN EN 2004-1和ASTM E 1004来测量非磁性金属材料的电导率。由于集成了温度传感器，所有探头都适合进行温度校正的测量，并自动显示标准化为20°的电导率值 C（68°F）。 所有探头均以不同的频率工作，因此能够测量各种材料深度。 使用的测量方法可以进行无接触测量，也可以在非导电面漆（如漆面或塑料盖）下进行测量。可用于：

        • 物料分类
        • 检查热损伤和材料疲劳
        • 关于热处理材料的硬度和强度的结论
        • 金属纯度的测定
        • 合金质量标准
        • 热喷涂层评估
        • FS40LF，用于测试硬币合金和小贵金属的真伪的附加功能
