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(jìn)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(gè)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(gè)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(gè)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(hù)。
COULOSCOPE® CMS STEP可以通過定位于電位-時(shí)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(gè)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(diǎn)：
1、根據(jù)庫侖電量分析法進(jìn)行測量，符合 DIN EN ISO 2177、50022 和 ASTM B764標(biāo)準(zhǔn)
2、可以簡便的對鎳鍍層之間的電化學(xué)的電位差進(jìn)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(dāng)中，“電勢差”和“電位差”則普遍應(yīng)用于一切電現(xiàn)象當(dāng)中。
