Model E-201-C-9 Combi natio n Electrode Operatio n In struction E-201-C-9型复合电极使用说明 Application 用途 Model E-201-C 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. 本电极是玻璃电极和参比电极组合在一起的复合电极，用于测量水溶液的 pH值。它广泛应用于化轻工业、制药工业、染色工业 和科研机构中需要检测水溶液 PH值的场合。 Specification 规格 Measuring range 测量范围：0-14 pH Measuring temperature 测量温度：0-60 °C Zero potential 零电位：7 ±5pH(25 C) Slope 斜率：(PTS) > 98.5%(2C ) Internal resistance 内电阻：< 250MQ25 C) Alkali error 碱误差:0.2pH(1M Na+ pH14) (25 C) Response time 响应时间：towards 95% equilibrium value, less than 1 sec./ 对于 95% 均衡值，少于 1 秒。 Operation and maintenance 使用和维护 Before measuring, electrode must be calibrated with standard buffer solution. 测量前，电极必须用标准缓冲液校准。 Sensitive glass bubble is not allowed to touch with hard substances. Electrode wills no effective if any rubbing is made. 敏感玻璃球泡不要与硬物接触，任何破损和擦毛都会使电极失效。 When measurement finished, put electrode in the cap, this has a bit of KCL solution in it. 完成测量后，应将电极保护帽套上，帽内应放少量氯化钾溶液。 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. 复合电极的外参比补充液为 3 mol/1 KCL (20ml蒸馏水和3 mol/L KCL混合)，补充液可从上端小孔加入。 Plug of electrode must be kept clean and dry. Short circuit of two ends of the plug is prohibited. 电极的插头必须保持清洁和干燥，绝对防止输岀端两端短路。 12 E lectrode should be matched with pH meter that has high input impedance( Q) > 10 电极应与高输入阻抗(> 110 Q 的 pH计配套。 Electrode mustn ' t be dipped in distilled water, protein solution or acid fluoride solution for long time. It mustn ith organic silicon grease. 电极避免长期浸在蒸馏水、蛋白质、酸性氟化物溶液中，并防止和有机硅油脂接触。 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，把电极敏感球泡端浸泡在 4%HF(氢氟酸)中3-5秒，用蒸馏水洗净，浸泡在 KCL溶液中使之复新
