TitroLine® 7500 KF – Automatic Titrator for volumetric water determination

  • The TitroLine® 7500 KF is a compact, easy-to-use volumetric titrator for water determination according to Karl Fischer (KF) with a typical operating range of 0.1 % – 100 % water.
  • The TL 7500 with 5, 10 or 20 ml burette has an exceptional high visibility full color graphic display which allows viewing even at extreme angles. The titration curve, but also other information such as ml, drift in µg/mL and µA-value are clearly displayed on the display.
  • The three USB, two RS 232 and Ethernet interfaces makes the TL 7500 KF highly communicative.
  • The parameters can be customized in each of the up to 50 methods.

  • Volumetric KF titration
  • Ready to use standard methods for standardization of the titrant and sample titration for 1- and 2-Component KF titrants.
  • Statistical functions including average value and relative standard deviation
  • Configurable output: Short, Standard with curve, GLP
  • Formula editor for individual calculations
  • Output of results in ppm,%, mg, μg, mg / l. Unit individually adjustable
  • Also suitable for the determination of bromine number and other dead stop titrations such as SO2 in wine and other food products.
  • Can be used also for dosing tasks such as sample preparation based on the sample weight.
  • The addition of the solvent and the extraction of the titrated sample are carried out by titration stand at the push of a button (Included with all sets)
