Product Description

Large user touch panel – convenient operation: The MKV-710S titrator comes with a large TFT colour touch screen. This volumetric Karl Fischer Titrator can be equipped with a second built-in burette (option) which enables it to perform automatic Karl Fischer factor determinations at a single keystroke. It is even possible to execute such factor calibrations automatically at regular time intervals.

Titrant information directly stored in the burette
Relevant titration information is stored in an IC chip in the burette unit. Changing the burette unit from one titrator to another does not require any re-entry of the titrant information. This prevents errors due to wrong reagent data.

Paper saving
Paper saving and environmentally friendly – results no longer need to be printed: Measurement results are converted to PDF and can be stored in a USB flash drive.

No need to adjust settings for different types of reagents and samples
KEM’s proprietary technology (endpoint detection by compensating liquid resistance, Japanese Patent No.1896338) makes it unnecessary to change the detection electrode sensitivity and the endpoint voltage depending on the nature of each solvent and sample. This feature reliably prevents over titration and ensures highly accurate measurements.

Software

Soft Cap Data Capture Software

  • Software CaptureThe easy way to transfer your results directly to Microsoft EXCEL
  • The Data Capture Software is an easy to use and flexible solution to collect measurement results from different KEM instruments (Refractometers, Density Meters, Potentiometric or Karl-Fischer Titrators, Thermal Conductivity Meters) on a Windows personal computer.
  • Up to four different instruments can be connected to one single PC and be used simultaneously. Two of these instruments can be of the same model.
  • The results can directly be stored in EXCEL workbooks. The measured results are always available at a glance in a clear and concise manner.
  • As soon as a measurement has finished, the result appears in the corresponding worksheet.
  • The layout, order and the format how the results are stored in EXCEL can freely be adapted to specific needs.
  • Results can be automatically be processed by EXCEL macros as they are transmitted to the PC. Additional data (comments, sample data, etc.) can be entered at any time by means of the PC keyboard or a barcode reader.
  • All results can at the same time be stored in as CSV files.

Accessories

Printer

IDP-100 PrinterIDP-100 Printer
Dot matrix ink printer for GLP compliance.

  • Dot matrix printer with ink ribbon, prints on regular paper (width 57.5 ± 0.5mm).
  • 24 digits, 144 dots per line.
  • Automatic paper end detection – no loss of data!
  • 2 kB internal buffer memory. Advantage: Less time required per measurement, as the instrument does not have to wait until the results are printed out.

Evaporator

ADP-611: Accurate water determinations of difficult samples
ADP-611 EvaporatorThe ADP-611 substantially broadens the application spectrum of your Karl Fischer Titrator. With this evaporator accurate water determinations of samples which cannot be titrated directly can be performed:

  • Substances which cause side reactions with the KF reagent such as copper (II) salts, iron (III) salts, nitrites, motor oils with additives, etc.
  • Substances that release water only at elevated temperatures like plastics
  • Substances which would contaminate the titration cell like coal dust, carbon black, etc.
  • Substances that are poorly soluble or insoluble such as cotton, paper, compressed wood, etc.

The ADP-611 features a modern microprocessor control ensuring maximum precision, reliability and user-friendliness:

  • Easy method development: A patented scan mode automatically determines the optimal evaporation temperature based on the relation between released water and heating temperature.
  • Rapid rise and accurate control of the heating temperature.
  • Digital display of temperature and flow rate.
  • Automatic alarm if the set temperature cannot be reached within a certain time or if the temperature in the oven exceeds 350°C.
  • Serial interface which enables the evaporator to be remote controlled by the MKA-610 and MKC-610 Karl Fischer titrators.
  • To safely avoid contamination from atmospheric moisture the ADP-611 is equipped with a remote controlled motor driven magnetic bar to move the sample from the sample chamber into the oven.

The heating chamber is equipped with an electrically conductive transparent heater glass. This permits the sample condition to be monitored during the vaporization process.

The ADP-611 comes with two built-in desiccant tubes for the carrier gas. With an optional air pump, air instead of nitrogen can be used as carrier gas.

Solvent Pump

Automatic Solvent Pump - Automatic Filling and Emptying System for Titration CellAutomatic filling and emptying system for titration cell
Direct contact with Karl Fischer Reagents should always be avoided. This automatic filling an emptying system for the titration cell (ordering number 98-433-0135) protects operators from direct contact with toxic reagents and vapors. The pump is built into the magnetic stirrer. The connecting cable for the stirrer is included in the standard delivery.
