A,purpose

The electrode is composed of an indicator electrode platinum wire and a silver chloride reference electrode. The saturated potassium chloride colloid solution is used in the printed circuit board, and the on-line measurement of oxidation reduction potential in the treatment of chromium containing wastewater is carried out5-70 C.

Two,Main technical parameters

1Electrode potential: 245-270mv(15PREFIX = ST1 -30 C)

2Reference electrode resistance: Less than or equal to10K?

3Electrode stability: .8mv/24

4,Electrode: Good conduction

Three,Maintenance and precautions

1,When the electrode is measured, the test section of the electrodeThe platinum wire and the reference liquid) must be immersed simultaneously.

2,The standard solution of the electrode, the hydroquinone saturated solution, was kept for48H. The preparation of a saturated solution of hydroquinonePH4.00Buffer, the addition of excessive hydroquinone, so that it is saturated

3,If the platinum wire of the electrode is stained with grease, the cotton can be dipped in acetone or alcohol, gently scrub clean, if stained with dirt is not soluble inorganic compounds, can be used30-50%Scrub the hydrochloric acid, every day can also use a clean toilet paper.
