High Precision / High Resolution
● Adopts a borosilicate hard-glass burette with a low expansion coefficient and low temperature-induced volume error to deliver high-precision infusion at a burette division of 1/20000. Infusion accuracy reaches ±10 μL (10 mL), which is better than the relevant JJG 814 and ISO 8655-2 standards.
● Based on a highly integrated ceramic-based measurement and control circuit, digital photometric, temperature, and potential electrodes are designed to enable in-situ photothermal signal measurement.
● Uses a high-frequency sampling data filtering algorithm, double-precision floating-point processing mode, and a high-speed processing unit to ensure ultra-high effective data resolution and accurate, reliable results.
● Employs advanced neural network and PID control algorithms to precisely control the endpoint infusion process and obtain the most accurate endpoint value.

Audit Trail
● Meets the relevant requirements of GXP, FDA 21 CFR Part 11, and other applicable laws and regulations, enabling full audit trail functionality without requiring a computer.
● Provides password aging management. The operator’s identity can be confirmed via password login or biometric identification. Operators with different identities are assigned corresponding levels of operational authority. Actions and comments for each step on the titrator are automatically stored and can be displayed and queried by stage in the work log.
● Measurement data are permanently stored. All data-related information—such as operator, operation time, experimental process, and equipment used—can be traced back, and any data modifications are recorded.
