Key Benefits
- Automatic electrode recognition — wireless recognition of SI Analytics ID electrodes eliminates setup errors and simplifies electrode management
- 50 user-programmable methods — password-protected method storage for standardised titration sequences across operators and shifts
- Expandable to full automation — optional 42- or 72-position sample changers and TitriSoft PC software upgrade the base unit to automated batch processing
- Multi-parameter capability — pH/mV, dead-stop (polarisation), and temperature inputs in a single instrument for acid-base, redox, ISE, and photometric titrations
Overview
The SI Analytics TitroLine 7000 is a high-performance automatic titrator designed for routine potentiometric titration in chemical, pharmaceutical, food and beverage, water, and environmental laboratories. It provides high-resolution pH/mV measurement alongside dead-stop endpoint detection, enabling accurate multi-parameter determination from a single instrument. Automatic wireless recognition of SI Analytics ID electrodes eliminates setup errors and streamlines electrode management across multiple operators.
Up to 50 user-programmable methods with password management allow each laboratory to build and protect application-specific titration sequences. Preloaded default methods cover the most common determinations — alkalinity, total hardness, acidity, chloride, SO₂, and TAN/TBN — reducing configuration time for standard workflows. Interchangeable burette heads (5, 10, 20, or 50 mL) adapt the instrument to any titration volume requirement, and the modular design allows upgrade from a basic unit to fully automated operation with a 42- or 72-position sample changer.
A 3.5-inch full-colour TFT display with wide viewing angle provides clear visibility in any laboratory orientation. RS-232, USB, and Ethernet connectivity supports integration with LIMS systems and the optional TitriSoft 3.3 PC software for advanced method development, data logging, and multi-instrument control.

Frequently Asked Questions
What titration methods are preloaded in the TitroLine 7000?
The TitroLine 7000 includes preloaded default methods for alkalinity, total hardness, acidity, chloride, SO₂, and TAN/TBN (acid/base number in oils). Up to 50 additional user-programmable methods can be stored with password protection.
Can the TitroLine 7000 be upgraded for automated sample processing?
Yes. The base unit can be expanded with an optional 42- or 72-position sample changer for automated batch processing. The optional TitriSoft 3.3 PC software provides advanced method management, data logging, and multi-instrument control for high-throughput workflows.
What types of titration does the TitroLine 7000 support?
The instrument supports potentiometric titration (pH/mV), dead-stop (polarisation) endpoint titration, ISE (ion-selective electrode), redox/ORP, and non-aqueous titration for TAN/TBN determination. Four titration modes are available: linear, dynamic equivalence point, endpoint-based, and pH Stat.
How does automatic electrode recognition work?
SI Analytics ID electrodes contain embedded identification that the TitroLine 7000 reads wirelessly on connection. The instrument automatically configures the correct measurement parameters for the attached electrode, eliminating manual setup and reducing the risk of operator error.
