Product Description

Convenient operation, versatile, expandable: The MKC-710M comes with the largest titration user interface available in the market: The MCU-720M control unit of this model with its 8.4 inch LED touch panel offers an unique user experience and can serve as a common controller for up to four titrators of any type, be it additional MKC-710B coulometric or MKV-710B volumetric Karl Fischer moisture titrators or even AT-710B potentiometric titrators.

Fast measurements
A new acceleration amplifier provides faster electrolysis with a maximum electrolytic speed of 2.6 mg H2O/min. This shortens the time required for pre-titrations and sample measurements considerably.

Increased workplace safety
With optional Bluetooth® adapters, there is no need for a cable connection between the control unit and the titrator. This offers substantial benefits in terms of safety as the main control unit can be located outside the hood when toxic samples have to be measured.

Unique flexibility
The MKC-710M is based on a new approach in terms of modularity. The core part of the system, the MCU-710M control unit, is a versatile, touch panel controlled titration work station which can control up to four KEM 710 titration units of any type. This saves space, time and money: If you need a system to perform volumetric Karl-Fischer moisture determinations or even potentiometric titrations in the future, you can easily upgrade your system without needing to invest money and waste valuable bench space for an additional display and spending time to get familiar with a new user interface.

Full GLP compliance
The MKC-710M offers comprehensive GLP functions which ensure that system performance checks are performed at regular intervals. Up to 100 records of system performance checks and Karl Fischer reagent factor determinations are stored in the MCU-710M control unit.

Now comes with an included flexible qwerty keyboard.

Soft Cap Data Capture Software

SOFT CAP Data Capture Software

The 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.

Printer

IDP-100 Printer

IDP-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 Evaporator

ADP-611: Accurate water determinations of difficult samples

The 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.

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.
