德國菲希爾COULOSCOPE® CMS STEP電位差測試儀的經(jīng)銷商-凱迪亞儀器為您提供各款進口電解測厚儀、多層鎳電位差測試儀！
在電鍍行業(yè)中，對多層鎳鍍層中各鍍層的厚度和電極電位的測定變成了一個越來越重要的需求。的多鍍層組成為不含硫的半光亮鎳層和含硫的光亮鎳層。這兩個鎳層之間足夠的電位差導(dǎo)致了光亮鎳層優(yōu)先腐蝕于半光亮鎳層，因此延遲了整個鎳層的穿透速度，并且給了基材相對于單鍍層更好的防腐保護。
COULOSCOPE® CMS STEP可以通過定位于電位-時間表中相關(guān)部分的雙指針來方便地測出鍍層厚度和電位差。這個圖表能夠外部保存或通過RS232轉(zhuǎn)換到PC電腦中。
COULOSCOPE® CMS STEP電位差測試儀的特點：
1、根據(jù)庫侖電量分析法進行測量，符合 DIN EN ISO 2177、50022 和 ASTM B764標準
2、可以簡便的對鎳鍍層之間的電化學(xué)的電位差進行測量，可以用于測量銅基層、鎳多層涂層和鉻涂層的厚度。
電位差，也稱作電勢差或電壓，是衡量單位電荷在靜電場中由于電勢不同所產(chǎn)生的能量差的物理量。電位差的國際單位制為伏特(V，簡稱伏)，常用的單位還有毫伏(mV)、微伏(μV)、千伏(kV)等。此概念與水位高低所造成的“水壓”相似。需要指出的是，“電壓”一詞一般只用于電路當中，“電勢差”和“電位差”則普遍應(yīng)用于一切電現(xiàn)象當中。
