Potentiometric Titrator
Potentiometric Titrator – ToronAPT™ 2000 (Automated)
Potentiometric Titrator (ToronAPT™ 2000) is a fully automatic system built for fast, precise, and repeatable titrations across many analytical workflows. It uses high-resolution potential (mV) measurement and automated reagent delivery to identify endpoints without visual indicators, reducing operator subjectivity and improving result consistency.
Designed as a compact all-in-one platform, ToronAPT™ 2000 combines a high-precision syringe burette, intelligent endpoint detection, and a large 10-inch capacitive touchscreen. It supports multiple titration modes and chemical methods, making it a strong fit for routine QC testing and advanced analytical labs that want dependable potentiometric titration with minimal manual steps.
Potentiometric Titrator – ToronAPT™ 2000 (Automated) Applications

Potentiometric Titrator – ToronAPT™ 2000 is suitable for a wide range of titrations, including:
- Acid–Base Titrations: Measure acidity, alkalinity, and concentration for chemical, pharmaceutical, and industrial samples.
- Redox Titrations: Evaluate oxidation–reduction reactions used in environmental, metallurgical, and chemical analysis.
