- General Details
With its performance spectrum, the TL7000 total Acid/Base Number Analyzer is the ideal starting device for potentiometric titration with potential for expansion and automation. high-resolution and precise pH/ mV and “dead-stop” measuring interface, makes it possible to determine a wide range of parameters quickly, reliable and accurate.
• High visibility, full color display that can be easily viewed from a distance and at extreme angles.
• Reagent data is securely stored in the intelligent and interchangeable modules
• Includes up to three USB, one LAN and two RS232 ports for expansion and connection of devices
• Export the results as PDF or CSV, also to networks.
“Specific features for the TL7000
• Automatic wireless recognition of SI Analytics ID electrodes guarantee accurate calibration and measurements
• High resolution pH/mV-electrode and temperature inputs for pH, ISE, redox (ORP) or photometric titrations.

• Polarizable electrode input for set endpoint titrations („Dead-stop“)
• Linear (fixed increment) and dynamic equivalence point titration mode and titration to endpoints
• pH Stat titrations
• Single and continuous measuring function
• Formula editor for individual calculations
• User management/password
• Titrations with the new photometric sensor
• Dosing with up to two connected piston burettes per method
• Titration with external piston burette
