Description

1. Use The electrode consists of an electrode with a platinum indicator and an electrode with silver chloride, and the housing is made of plastic. It is filled with a colloidal solution of saturated potassium chloride, which is used for online measurement of oxidation potential in the treatment of PCBs and chromium wastewater. Applicable temperature 5-70 ℃.
2. Main technical parameters
         (1) electrode potential: 245-270mV (15-30 ℃)
         (2) reference electrode internal electrode resistance: ≤ 10K
         (3) Electrode stability: ± 8mV / 24 (4) Light electrode electrode: good conductivity
3. Use, maintenance and precautions
         (1) When measuring an electrode, the test portion of the electrode (including the platinum wire and the reference solution of the complex portion) must be immersed simultaneously.
         (2) Standard electrode solution - quinone hydroquinone saturated solution, storage time 48 h. (Nozzle: preparation of quinone hydroquinone saturated solution: add excessive quinone hydroquinone to ph4.00 buffer to make it saturated)
         (3) If the platinum wire of the electrode is painted with grease, it can be cleaned with a grease-free cotton soaked in acetone or alcohol. If the dirt is insoluble, INORGANIC, it can be cleaned with 30-50% hydrochloric acid. It can also be wiped down with clean, high quality toilet paper once a day
