ProductDescription : Use and maintenance :

1. Soak and clean the electrode surface with water before use. A variety of pH/mV meters can be used for determination, paired with calomel electrodes or silver chloride, the electrode is directly inserted into the sample, and the reading is stable.

2, in situ determination of soil, sediment, etc., especially need to be careful, do not make the end deformation, surface rough, temporary use can be soaked in water, long-term do not book dry put in the box.

3. After the electrode is used for a long time, the surface oxide film or adsorbent is heated to 70℃ by a mixture of 0.2MHc1v1-0.1MnAC1-0.2% Na2SO3 for 2 hours, and then potential E is detected in a quinone hydroquinone saturated potassium hydrogen phthalate solution of 0.05m, which should conform to the following formula:

E=455-0. 09 (T-25) - [59.1+0.2(T-25)pH

Where: pH is 0.05 pH value of potassium hydrogen phthalate solution at T℃.

3. When the electrode is used, try not to contact the sealant between the platinum sheet and the tetrafluororod with the liquid, (if you must contact, try not to contact for a long time) to avoid contact with the test liquid can extend the service life of the electrode.
