AELAB | Water Testing Equipment | Karl Fischer/Coulometric Titrator | Automatic Potential Titrator
An Automatic Potential Titrator is a laboratory instrument used to determine the concentration of analytes in a solution by detecting voltage (potential) changes during titration. It automates titration steps, ensuring high precision, reproducibility, and reduced human error in applications across pharmaceuticals, food, and environmental testing.
An Automatic Potential Titrator performs titrations by monitoring the change in electrical potential between indicator and reference electrodes as titrant is added. The endpoint is automatically detected by sharp changes in voltage, allowing accurate quantification of the target analyte. This automation improves analytical throughput and consistency compared to manual titration methods.
