high precision/high-resolution

• Using borosilicate hard glass burette with low coefficient of expansion and low temperature volume error to achieve1/20000The burette has a high-precision liquid feeding volume, with a liquid feeding accuracy of up to±10 μL（10mL）, superior toJJG 814TheISO 8655-2Standard related requirements

• Design digital photometric, temperature, and potential electrodes based on highly integrated ceramic based measurement and control circuits to achieve in-situ measurement of photothermal signals

• Using high-frequency sampling data filtering algorithm, double precision floating-point operation mode, and high-speed operation processor to ensure ultra-high effective data bits and accurate and reliable results

• Using advanced neural networks,PIDControl algorithms to precisely control the endpoint feeding process and obtain the most accurate endpoint value

audit trail

• No need for a computer to meetGXPTheFDA 21 CFR Part 11Implement full process audit tracking in accordance with relevant requirements in laws and regulations

• The fully automatic permanent stop titrator has a password time management function, which can confirm the operator's identity through password login or biometric recognition. Operators with different identities have corresponding levels of operation permissions. Every operation behavior and remark made on the titrator are automatically stored in the work log and can be displayed and queried in stages

• Each measurement data will be continuously monitoredSave all information related to the data, such as the operator, operation time, experimental process, and equipment used, which can be traced. Any modifications made to the data are also recorded
