Redox reaction is widely used in chemical reaction. In titration analysis, some substances can not be titrated by acid-base, precipitation and complexometric titration. Satisfactory results can be obtained by redox determination. Potential difference between oxidant and reductant is the basic basis for quantitative analysis of reaction.
Model ORP-411 instrument not only has the function of ORP potential measurement, but also has the function of pH measurement.
Dual power supply (battery and AC) is suitable for laboratory, physical and chemical laboratory, natural environment and field test.
