Scratch Hardness Testing

Model 435

裂纹并不总是美观的，至少不是在光滑、有光泽的涂层表面上。这通常很快：指甲在哑光桌子上无意间“划伤”。或者一根树枝划过凯迪拉克美观的漆面。小原因，大麻烦——一个裂纹！裂纹的一个变体是金属划痕。这里所指的是硬币等小金属颗粒这样的元凶，它们会“擦掉颜色”，从而在表面留下难看的划痕。以前，人们只能用指甲“检查”表面。435 型耐磨性测试仪首次实现以精确的测试值定义涂层表面的特性。

新的 - ERICHSEN SmartPen - 新一代的移动划痕硬度测试

对于表面的硬度测量，我们有多年来经过验证的硬度测试铅笔，型号318和318S以及型号435和435S，已经在各分支机构中得到了广泛的应用。有了这些测试设备，漆膜、塑料涂层等的硬度可以被确定、命名、记录并以数值的形式传达。无论在平坦或弯曲的表面上，小或大，仪器都可以随时使用，而且由于其体积小，易于运输。现在有了ERICHSEN SmartPen，一种带有数字测试力设置和显示（分辨率为0.05N）的模块化硬度测试笔。
