接触角测试仪 - CAT适用于几乎所有液体的润湿测量。该仪器是快速测量静态接触角的理想仪器,可用于简单的润湿测试,也可通过表面自由能对材料进行表征。
应用
检查塑料、玻璃、陶瓷、木材、纸张或金属的润湿性
分析表面清洁度
活化过程的质量保证,例如等离子处理、电晕处理或火焰处理
测试疏水涂料和其他涂料的效果
精准定量,且快速更换液体
移液器的体积微调和标准化的程序确保了测量结果具有高度可重复性。也可以将不同的液体进行一系列润湿测量,并具有较高的样品通量。
光学与图像综合评价
接触角测试仪的优质镜头和高分辨率相机能够以理想的尺寸和亮度在图像中显示出液滴,即使是非常小的液滴。
结合 ADVANCE 软件的智能图像评估算法,液滴形状分析可提供准确的接触角测量结果。 使用提供的参考对象,还可以快速确定图像比例,以测量绝对液滴尺寸,例如体积,作为测量结果和报告的一部分。
