Basic unit (scope of delivery please refer to the basic unit), with 10 ml exchangeable head, TM 235 KF titration stand with integrated stirrer and pump, titration vessel TZ 1770, micro double platinum electrode KF 1100,starter kit, power supply 100-240 V.
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 colour 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.
