Working Principle
The ZDJ-5D automatic titrator determines the equivalence point during chemical reactions by continuously monitoring changes in electrical signals generated by sensors.
During titration, the instrument automatically adds titrant through a precision burette while measuring the response signal from electrodes or optical sensors. The built-in intelligent algorithm analyzes the titration curve and automatically determines the endpoint using different calculation methods including differential analysis, preset endpoint detection and constant parameter control.
Depending on the selected module:
• Potentiometric titration detects potential changes caused by ion concentration variations.
• Conductometric titration determines endpoints through conductivity changes.
• Dead-stop titration detects current changes under controlled polarization voltage.
• Photometric titration identifies endpoint changes through optical signals.
• Temperature titration determines reaction completion through temperature variation.
