水滴角测试仪试验原理:
所谓接触角,是指在一固体水平平面上滴一液滴,固体表面上的固—液—气三相交界点处,其气—液界面和固—液界面两切线把液相夹在其中所成的角即为接触角。
水滴角测试仪产品特性:
1. *设计的机械结构,多维协调控制样品台、进样系统、摄像系统的运作,随意调整,平稳性高、水平性好;
2. 背光源采用可调亮度的LED冷光源,保证了液滴轮廓清晰可见。冷光源亦可有效避免额外热度所导致的小液滴挥发现象;
3. 专业设计的手动进样系统,微距离移动灵活方便,*配合微量进样器,使进样更为精确、方便;
4. 工业级高清CMOS相机配合可连续变焦显微镜镜头,采集图像清晰不失真,成像分辨率达2048H×1536V;
5. 视频实时监控测试区域,可瞬间冻结和连续抓拍试样图像信息,抓拍周期可设定;
6. 软件提供多种专业的测试方法和解析方式,适用于多种类型样品和滴液形态的测试;
7. 软件可多种方式求取接触角值:左右接触角值可分别计算与比较,及自动测试和人工修整相结合,以达到更为精确的测试结果;
8. 软件可进行图象数据的保存、打印和调入再分析,操作简单、测值准确。
