  • Description
    Automatic Titrator for exchangeable heads for potentiometry and KF

    The Titroline® 7750 is the all-rounder for both potentiometric titration and volumetric KF titration. The TitroLine® 7750 combines the features of the potentiometric titrator TitroLine® 7000 and the volumetric Karl Fischer titrator TitroLine® 7500.

    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® 7750
    • 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.
    • 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
