For many titrations, a potentiometric determination of the equivalence point is simply not possible. However, manually performing complexometric titrations can be inaccurate due to ambiguous color changes and when using non-aqueous or semi-opaque liquids, such as lubricating oils. In these cases, the use of a photometric probe for the optical determination of an endpoint during volumetric analysis is preferred. Hanna Instruments introduces HI900601 photometric electrode for when a color change is still the best solution.
