GT70 Fully Automatic Potentiometric Titrator
Product Overview
The GT70 Fully Automatic Potentiometric Titrator is designed for automated quantitative analysis using potentiometric endpoint detection. It supports acid-base, redox, precipitation, complexometric and non-aqueous titration methods, making it suitable for routine laboratory analysis in pharmaceutical, chemical, food, environmental and research applications.
The system provides high-precision closed-loop dosing control with a dosing resolution of 1 μL. It can automatically perform sample loading, titration, cleaning, result calculation, data recording and titration curve generation, reducing manual operation and improving measurement consistency.

Key Features
• Supports acid-base, redox, precipitation, complexometric and non-aqueous titration
• Two built-in titration dosing channels, expandable to up to 8 channels
• 1 μL dosing resolution with high-precision closed-loop control
• Corrosion-resistant PTFE tubing and imported PTFE rotary valves for acid and alkali titration
• Automatic instrument self-check, sample loading, pipeline cleaning and result recording
• Real-time display of titration curves and measurement results
• Automatic generation of pH–titrant volume curves
• Multi-level user management, audit trail and electronic signature functions for regulated laboratories

Working Principle
The GT70 determines the titration endpoint by continuously measuring the potential or pH of the sample during titrant addition. According to the selected titration method, the instrument precisely delivers the titrant through a motorized dosing unit while monitoring the electrode response.
The system can perform endpoint titration, equivalence-point titration and dynamic titration. Measurement data are processed automatically to determine the endpoint and calculate the final analytical result. The real-time titration curve allows users to monitor changes in pH or potential throughout the titration process.
