Laboratory pH meter electrode instead of importing the problem of


Clarify these issues later method, the electrode can be replaced to work. Electric meter electrode into IZI IZI then the electrode interface is inconsistent with the domestic, is the electrode instead of the important issues faced. To progress with the IZI complex electrode apparatus, for example, the failure of the electrode into the IZI cut from the roots to retain the electrode lead (hereinafter referred to as \We then Shanghai Lei magnetic Instrument Factory production \mercury electrode jack. If we are going to use electrodes made of the E201 instead of imported composite electrode,[link widoczny dla zalogowanych], the shielding can open the converter box, the original electrode leads from the electrodes inserted glass electrode jack converter, and the original electrode lead of the converter boxes with cored wire connected within and q9 connector wire leads welded together, the original line and the shielding electrode leads and Q9 connector converter box connected to the shield wire welded together, re-assembled shielded converter boxes. We only use the original electrode lead connected to the electricity meter, E201-made composite electrode connectors and converters Q9 Q9 Q9 transition joint by joint connection. Measurement and Testing Technology 1999 ・ No. 2 If you intend to replace the original with a matching electrode electrode into the El station complex, you can open the shield box converter, the converter's Q9 lead solder joints, using the original place of the electrode lead connector converter lead on the Q9. Welding should be remembered, because the glass electrode is high impedance signal source, the original wire electrode leads should be connected with the glass, extreme power, the original lead of the shield electrode and calomel electrode Duanxiang should be connected, and then re-assemble the conversion Shielding Box. Use, as long as the glass electrode and reference electrode are connected to the corresponding jack converter, the original electrode lead can be connected to the electricity meter. Similarly,[link widoczny dla zalogowanych], for the use of imported equipment supporting the electrode, the light of the above approach can also be processed. Converter with electrodes, each electrode can make it particularly easy to replace, while the converter shielding effect of the welding point play, to prevent interference measurements. Again, the welding point is the high resistance in the insulation inside the converter shelf, without causing the input impedance of electric meter drop. 3. Notes 3.1 instead of electric meter parts department should be measured by the test, to determine its impedance House, House people current, zero potential pH, temperature compensation. Meet the requirements discussed above pH meter,[link widoczny dla zalogowanych], the electrode can be replaced. Instrument total input impedance by Jiangxi people side of the insulation resistance and input impedance in parallel to the decision, some instruments as long-term use by the environment of dust and moisture effects, House of people end insulation lamps down, so that input A drop in impedance , of such equipment should be insulated. It should also be aware that welding converter cable, you should avoid electrode inserted IzI, House insulation resistance of one side stand down. Because instead of increased when the electrode converter, the converter should be used as part of the instrument, the measurement converter department of the matching portion of the electric meter test, to achieve the above requirements, be carried out instead. 3.2 The measurement functions with other ions or acidity, the value of the other electrodes can be adjusted often, instead, just replace the electrode by use of zero potential pH of zero potential to set the instrument to be (generally choose to 7). In summary, for failure or damage caused by electrode idle import acidity, perfectly measured through the departments of JJG119-84 laboratory pH meter verification procedures for examination. Determine the House impedance, Jiangxi people current, zero potential electrode pH value and is connected with the integrated converter station when the House impedance, the current House of people, the reference methods described above, the electrodes instead. Practice has proved that this method is simple and worth promoting. ■ [References] 1. Hou Chuan JC, Zhang Yan groups weigh pH. Du {dry volume published in China. 19932. Xie Fu.

In 1985,[link widoczny dla zalogowanych], Taiwan will be May 99, Registration of Product Certification implementation of the new approach, implemented over the years in Taiwan to cancel the production and import of commodity inspection and batch testing system. \type testing and total quality management and assurance system registration system can improve inspection efficiency. Their registered goods, printed in standard certification mark, sign and famous, you can remove the factory or imported through approved testing procedures, can save businesses time, but also the interests of the public to provide a guarantee.
