显微测厚仪产品简介
本款显微测厚仪系统依据ASTM D
5796制造，是金属卷材上单层和多层涂料的指定测厚系统，本系统通过自带的精密打孔装置在样品上钻取微孔，显微光学系统将微孔放大至400倍通过软件一次性分别精确测量每个涂层的厚度，完全不受涂层化学性质的影响，是目前所有测厚系统中最精确的多层测厚系统。可以精确、便捷的量测干膜厚度。
本款显微测厚仪产品特点
◆Can measure the thickness
of each coating layer and whole coating layers at one time
各个涂层厚度一次性获取
◆Can save and print data of each coating layer
各涂层数据通过电脑保存或者打印机输出
◆Accurate measurement results based on 4 times, 8 times repeatable
measuring
通过4次或者8次的定向测量，从而达到无与伦比的重复性
◆No coating material limitation
不受涂层、镀层材质和工艺的影响
◆No need to calibrate
无需校准
◆No
operator’s error
操作简便直接，成功避免误操作
◆Fast and accurate layer
distinction among each coating layer
通过随机量测软件清晰便捷的界定各涂层
◆Easy to
upgrade
容易升级
◆Wide application scope of Optical System such as length
measurement, surface defect, paint film fault, etc.
光学系统还可以同时用于涂镀层表面缺陷的检视
◆Low maintenance
结构简洁精密，几乎无需维护
显微测厚仪测试原理（系统如何实现高精度的测量）
◆Crater
on the coating surface using a precise borer bit.
精密的打孔装置在样品表面一次性形成一个深度达到基材的圆润的微孔
◆A shallow hole generated by the borer
bit reveals each different coating layer from the substrate to the top coating.，
Through a video microscope and high -resolution monitor, magnified bored-hole
can be displayed and examined; The magnified crater displays each coating layer
from the substrate to the finish coating layer.
如图一所示，通过微孔展示的经光学显微系统和软件处理的从基材到里层和表层的层间结构
◆The image on the screen can be
magnified 400 times.
显微光学系统可以将微孔高保真放大至400倍
◆The thickness measurement of
the coating layer is made by lining the crosslines (4 crosslines, 8 crosslines)
from the beginning point to the ending point and measuring the distance between
the 2 points with digital micrometer.
各涂镀层的厚度通过在4个座标方向或者8个座标方向上的数字测距来精确得到
◆The actual thickness of the coating
layer measured can be obtained by dividing the measured distance by 10. (Feature
1)
如图二所示，a和b分别表示了两个涂层的厚度
