顯微測厚儀產品簡介本款顯微測厚儀系統依據ASTM D 5796制造，是金屬卷材上單層和多層涂料的指定測厚系統，本系統通過自帶的精密打孔裝置在樣品上鉆取微孔，顯微光學系統將微孔放大至400倍通過軟件一次性分別精確測量每個涂層的厚度，完全不受涂層化學性質的影響，是目前所有測厚系統中*精確的多層測厚系統。可以精確、便捷的量測干膜厚度。本款顯微測厚儀產品特點

◆Can measure the thickness of each coating layer and whole coating layers at one time

各個涂層厚度一次性獲取

◆Can save and print data of each coating layer

各涂層數據通過電腦保存或者打印機輸出

◆Accurate measurement results based on 4 times， 8 times repeatable measuring

通過4次或者8次的定向測量，從而達到****的重復性

◆No coating material limitation

不受涂層、鍍層材質和工藝的影響

◆No need to calibrate

無需校準

◆No operator’s error

操作簡便直接，成功避免誤操作

◆Fast and accurate layer distinction among each coating layer

通過隨機量測軟件清晰便捷的界定各涂層

◆Easy to upgrade

容易升級

◆Wide application scope of Optical System such as length measurement， surface defect， paint film fault， etc.

光學系統還可以同時用于涂鍍層表面缺陷的檢視

◆Low maintenance

結構簡潔精密，幾乎無需維護

顯微測厚儀測試原理（系統如何實現高精度的測量）◆Crater on the coating surface using a precise borer bit.

精密的打孔裝置在樣品表面一次性形成一個深度達到基材的圓潤的微孔

◆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.

如圖一所示，通過微孔展示的經光學顯微系統和軟件處理的從基材到里層和表層的層間結構

◆The image on the screen can be magnified 400 times.

顯微光學系統可以將微孔高保真放大至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.

各涂鍍層的厚度通過在4個座標方向或者8個座標方向上的數字測距來精確得到

◆The actual thickness of the coating layer measured can be obtained by dividing the measured distance by 10. (Feature 1)

如圖二所示，a和b分別表示了兩個涂層的厚度
