PH復(fù)合電極中英文對(duì)照說(shuō)明書(shū)
Model E-201-9 Combination Electrode Operation Instruction
E-201-9型復(fù)合電極使用說(shuō)明
I. Application用途
Model E-201-9 electrode is combined by glass electrode and reference electrode for measuring Ph value in water. It is widely used in chemical light industry, pharmaceutical industry, dye-works and scientific institute where pH value needs measuring.
本電極是玻璃電極和參比電極組合在一起的復(fù)合電極，用于測(cè)量水溶液的pH值。它廣泛應(yīng)用于化輕工業(yè)、制藥工業(yè)、染色工業(yè)和科研機(jī)構(gòu)中需要檢測(cè)水溶液PH值的場(chǎng)合。
II. Specification 規(guī)格
1. Measuring range測(cè)量范圍: 0-14 pH
2. Measuring temperature測(cè)量溫度: 0-60℃
3. Zero potential零電位: 7±0.5pH（25℃）
4. Slope斜率: （PTS）≥98.5%（25℃）
5. Internal resistance內(nèi)電阻:≤250MΩ（25℃）
6. Alkali error堿誤差 : 0.2pH（1M Na+ pH14） （25℃）
7. Response time響應(yīng)時(shí)間: towards 95% equilibrium value, less than 1 sec./對(duì)于 95%均衡值，少于1秒。
III. Operation and maintenance使用和維護(hù)
1. Before measuring, electrode must be calibrated with standard buffer solution.
測(cè)量前，電極必須用標(biāo)準(zhǔn)緩沖液校準(zhǔn)。
2. Sensitive glass bubble is not allowed to touch with hard substances. Electrode wills no effective if any rubbing is made.
敏感玻璃球泡不要與硬物接觸，任何破損和擦毛都會(huì)使電極失效。
3. When measurement finished, put electrode in the cap, this has a bit of KCL solution in it.
完成測(cè)量后，應(yīng)將電極保護(hù)帽套上，帽內(nèi)應(yīng)放少量氯化鉀溶液。
4. Outer reference solution of combination electrode is 3 mol/L KCL solutions （Mix 20ml distilled water with 3 mol/L KCL）. Solution can be poured from small hole under the cap.
復(fù)合電極的外參比補(bǔ)充液為3 mol/1 KCL （20ml蒸餾水和3 mol/L KCL混合），補(bǔ)充液可從上端小孔加入。
5. Plug of electrode must be kept clean and dry. Short circuit of two ends of the plug is prohibited.
電極的插頭必須保持清潔和干燥，防止輸出端兩端短路。
6. Electrode should be matched with pH meter that has high input impedance（≥1012Ω）
電極應(yīng)與高輸入阻抗（≥1012Ω）的pH計(jì)配套。
7. Electrode mustn’t be dipped in distilled water, protein solution or acid fluoride solution for long time. It mustn’t’ touch with organic silicon grease.
電極避免長(zhǎng)期浸在蒸餾水、蛋白質(zhì)、酸性氟化物溶液中，并防止和有機(jī)硅油脂接觸。
8. If slope drops, dip sensitive bubble of the electrode in 4% HF solution for 3-5 sec. clean with distilled water, dip in KCL solution to make it renew.
如果斜率下降，把電極敏感球泡端浸泡在4%HF（氫氟酸）中3-5秒，用蒸餾水洗凈，浸泡在KCL溶液中使之復(fù)新。
9. If bubble is contaminated or liquid junction is blocked, sensitivity of electrode will be influenced. Clean with proper detergent.
被球泡受污染或液接界堵塞，電極靈敏度會(huì)受影響，此時(shí)應(yīng)用適當(dāng)清潔劑清洗。
