Description:
The electrode is made of an indicator electrode, a platinum slice and a silver chloride reference electrode, and the shell is made of plastic. The saturated potassium chloride colloidal solution was applied to on-line measurement of oxidation-reduction potential in printed circuit board (PCB) treatment of chromium containing wastewater, with a temperature of 5-70 DEG C.

Specification:
1. Electrode potential: 245-270mv (15-30 degrees Celsius)
2. The electrode reference electrode resistance: less than 10k
3. The stability of electrode: 8mv/24.
4. Electrode indicating electrode

Note：
1. In the measurement of electrode, the electrode test part (including platinum wire and reference liquid parts) must be immersed simultaneously.
2. The standard solution of electrode - saturated solution of hydroquinone hydroquinone, the storage time is 48h. (attachment: preparation of the saturated solution of hydroquinone hydroquinone: in the PH4.00 buffer, add an excess amount of hydroquinone hydroquinone to make it saturated)
4. A platinum wire electrode if stained with grease, can skim cotton with acetone or alcohol, gently scrub clean, if the contaminant is soluble inorganic material, used 30-50% hydrochloric acid cleaning, can also use advanced toilet paper to clean the once a day
