MKH-700 Hybrid Karl Fischer Titrator

Hybrid Karl Fischer Titrator MKH-710

Gone are the days when people had to worry about whether a Karl Fischer coulometric or volumetric titrator was the appropriate solution for their applications – worries about the correct sample size and tedious reagent

Product Description

Gone are the days when people had to worry about whether a Karl Fischer coulometric or volumetric titrator was the appropriate solution for their applications – worries about the correct sample size and tedious reagent factor determinations with water standards are now things of the past.

The MKH-710 ushers in a new era of Karl Fischer Titration: It is the first Karl Fischer Titrator which can do both, volumetric and coulometric Karl Fischer titrations. The MKH-710 seamlessly combines both methods, adapting the titration procedure perfectly to the water content and nature of the sample being measured.

Coulometer? Volumeter? Hybrid!
The Hybrid Karl Fischer Titrator not only performs both, volumetric and coulometric Karl Fischer titrations: Depending on the water content of the sample, the hybrid titrator automatically applies the most appropriate procedure to perform the titration. This ensures maximum accuracy within the shortest possible measuring time.

Karl Fischer factor measurement – a matter of a keystroke
No water standards to inject, no weighing errors, less work: The instrument determines the factor of the Karl Fischer reagent by coulometric backtitration at the click of a button.

No need to worry about the correct sample size
No matter whether a sample contains 10 μg or 500 mg of water: The MKH-710 automatically applies the most accurate and quickest procedure to measure it.

Easy operation, trouble-free maintenance
A large capacity, easy to open titration cell with a large sample inlet and a generator electrode with replaceable membrane ensure easy operation and maintenance.

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.

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.

Titration Units and External Burettes

Automatic Piston Burette APB-610
APB-610 Automatic Piston BuretteThe Automatic Piston Burette APB-610 can be used either as stand alone precision burette to perform manual titrations or as an additional external burette for KEM titration systems based on an AT-510, AT-610 or AT-700 Titrator. The APB-610 allows to meter liquids with highest accuracy even under difficult circumstances:

  • The end of the feeding hose is equipped with a device which prevents diffusion.
  • The burette can be equipped with a temperature sensor to monitor the temperature of the liquid and to correct possible errors due to thermal expansion caused by variations of the surrounding temperature.
  • The glass body of the burette is shielded by a protection cover.
