TitroLine® 7800 Universal Automatic Titrators

Not yet rated

The TitroLine® 7800 enhanced the universal features of the TitroLine® 7750 with an additional IDS measurement socket. Hence the TitroLine® 7800 can perform potentiometric titrations with analog and IDS electrodes up to volumetric KF titrations. The digital (IDS) measurement socket allows the connection of various digital sensors, such as for measuring of conductivity.

General features

  • 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 TitroLine® 7800

  • 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.
  • Second digital measuring socket for intelligent digital pH-, conductivity, ORP sensors (IDS)
  • Perfect for non-aqueous titration such as acid and base numbers in oils (TAN and TBN)
  • Polarizable electrode input for set endpoint titrations ("Dead-stop" + KF)
  • Linear (fixed increment) and dynamic equivalence point titration mode and titration to endpoints
  • pH Stat titrations
  • volumetric KF titrations
  • Single and continuous measuring function
  • Formula editor for individual calculations
  • User management/password

Latest features

  • Titrations with the new photometric sensor OptiLine 6
  • Dosing with up to two connected piston burettes per method
  • Titration with external piston burette
