Potentiometric Entry Level Titrator AT-710B

Maximum performance and efficiency at minimum costs without making any compromises in terms of operator convenience:
45 years of experience in manufacturing potentiomeric titrators and a myriad of valuable hints from our customers enabled us to achieve this ambitious goal. The AT-710B titrator not only offers the technical specifications and all the features you would expect from a high end titrator, it provides at the same time an extremely simple user guidance, a new comfortable approach for method development and editing, easy data exchange and almost unlimited expansion possibilities.
But there is much more: The AT-710B can grow with your needs. With the CHA-700 Sample Changer the AT-710B titrator can easily be upgraded to the most cost-effective, compact and user friendly automated titration system available in the market. And by adding a MCU-710M colour touch screen control unit you can easily upgrade it to a multi channel titration system, capable of running up to 4 titrations simultaneously.

Convincing specifications
The built-in high resolution burette of the AT-710B titrator ensures precise dosing and highly reproducible results. The burette has a resolution of 20'000 steps. An optimized design of the valve reduces the danger of air bubble formation to a minimum and an optional temperature sensor avoids measuring errors caused by ambient temperature fluctuations. If required, the instrument can be equipped with a second built-in burette.

Flexibly configurable and expandable
The AT-710 can control one or two built-in and up to 8 external burettes. It is available with built-in preamplifiers for potentiometric, conductometric and photometric titrations.
Furthermore, the user interface of the titrator can upgaded to a AT-710S or AT-710M titrator by simply connecting the corresponding MCU control unit.

No training required
When automated with an CHA-700 Sample Changer, the AT-710B titrator offers the simplest operation one can imagine. No buttons to click or methods to select in order to run different types of measurements one after the other or automatically in a row.

Smooth method input and method transfer
The AT-710B titrator offers a comfortable way to edit methods - without requiring a touch screen on the instrument itself: The methods are developed and stored on an USB memory stick by means of a personal computer and can easily be installed on one or several AT-700B Titrators.

Versatile data export
The AT-710B titrator offers convenient possibilities for measurement data acquisition and storage whether or not the instrument is permanently connected to a personal computer. Titration results including the titration curves can conveniently be stored as pdf files on an USB flash drive (memory stick).


A new standard in terms of ease of use

KEM's new intuitive operation concept makes a touchscreen based user interface in many cases redundant: No methods to select, no sample file to enter, no click required to run different types of measurements one after the other or automatically in a row. Instead of controlling the titrator with a costly touchscreen the operator controls it with a reasonably priced automation unit. The CHA-700 Sample Changer has no rotating turntable but six or eleven fixed positions. Each of these positions can be dedicated to a certain type of measurement. In order to perform measurements the operator only needs to know which type of sample comes into which position and to put it there – an easy task which does not require any training.

Comfortable input of measuring methods

Entering measuring methods on an instrument directly normally means annoying scrolling and time-consuming input of names and numbers on a small screen. The AT-710B offers a far more convenient way to enter measuring methods working on the big screen and the comfortable keyboard which is available to everybody: The methods can be developed directly on an USB memory stick on any personal computer - without needing to install any software. This concept does not only make method development more convenient, it makes it at the same time easier to install the same method on several AT-710B titrators and ensures that there is always at least one backup copy of your valuable methods.

Substantial accuracy and reliability enhancement

High resolution burettes, small dead volumes and automatic compensation of the influence of ambient temperature fluctuations: The AT-710 titrators come with all the prerequisites that ensure highly accurate results:

The burette drives have a resolution of 20'000 steps.

No more classical turning valve connected to the burette: The AT-710 titrators come with a newly developed valve mounted directly on top of the burette. Advantage: Less connecting tubes, which means less cross contamination when replacing reagents and less room for air bubble formation.

Fluctuations of the ambient temperature can cause measuring errors. With an optional temperature sensor the AT-710 titrators monitor the temperature of the titration reagent and correct errors due to volume expansion automatically.

Smooth data entry and control

Transmitting sample weights directly from a balance, inputting sample names with a barcode reader, entering sample codes with a numeric keypad: The AT-710 titrators offer all the interfaces and features required for a seamless integration into your workflow.

The AT-710B offers even the possibility to connect an Android device. The corresponding App can be used to start and stop titrations. It provides a real time display of the titration curves and facilitates the easy input of sample weights.

A system which grows with your needs

Whatever your titration needs will be in the future – your initial investment will never be lost: The AT-710B titrator can easily be upgraded to an AT-710S or to an AT-710M titrator by simply adding the corresponding MCU-710 control unit. It is thus possible to convert your stand alone titrator to a touch panel controlled titration system, capable of running up to 4 titrations of any type simultaneously – including volumetric or coulometric Karl Fischer titrations.

The ultimate in space efficiency

Bench space as it is normally limited. The AT-710 titrators deal very economically with this valuable resource: Even a fully fledged titration system consisting of an AT-710 Titrator and a CHA-700 Sample Changer does not occupy more than 365 mm of bench space – a new record in terms of space efficiency in the world of titration!

CHA-700 Sample Changer
CHA-700 Sample Changer

Zero Touch Operation: Unprecedented ease of use

The CHA-700 Sample Changer combines the advantages of an automation system with a totally new operating philosophy, which brings the conventional 'how many clicks are required per measurement' debate to an abrupt end: Zero Touch Operation does not mean fewer clicks required per measurement – it means no click at all!

The CHA-700 is an automatic titration stand with seven positions: One position is reserved for a beaker to clean and store the electrode. Each of the other six positions can freely be assigned to a certain type of measurement. To start a measurement, the operator simply needs to put the sample into the corresponding position – no method to select, no task list to fill, no start button to click. The system performs the titrations exactly in the order in which the samples have been put onto the tray. During operation, already titrated samples can continuously be replaced by new ones. This saves valuable time, as the operator does not have to wait for a titration to finish in order to put a new sample. Even urgent samples can be titrated immediately without needing to touch any key, performing the following fully-intuitive procedure: The operator lifts the less urgent samples briefly up to change the order in which they will be processed. That's it! As soon as all the samples are processed, the electrode returns to the reserved position and remains there.

Smallest space requirements with optimal functionality

A fully fledged Zero Touch Operation titration system hardly occupies more bench space than a normal potentiometric titrator with it's titration stand. It goes without saying that it is far more compact than any other automated titration system but there are three other important advantages compared to such systems:

  • There is no acceleration of a turntable which could cause the samples to spill over.
  • All the samples can easily be replaced at anytime, there is never a sample at the rear of the turntable which hardly can be reached.
  • Changing the order in which the samples are processed is an easy task: The samples only need to be lifted up in the desired order - no need to rearrange the order of the beakers on the tray.

Adaptable to your specific requirements

The standard version of the CHA-700 is designed to be used with 250 mL or 200 mL standard beakers or disposable cups. Thanks to optional adapters several or all positions can easily be modified to hold 100 mL beakers or 50 mL disposable cups.

The CHA-700 can control an external pump which allows to equip it with a powerful shower/drain system to thoroughly clean the electrode and the stirrer after titrations.

Convenient handling of titration data

Titration results are frequently printed out on A4 printers and/or archived on personal computers.
In certain cases, however, it is not ideal or even impossible to have a personal computer or an A4 printer near to the measuring system. In such cases, the Tview6 software is the ideal solution:

  • The AT-610/AT-510 Automatic Potentiometric Titrators and the MKA-610/MKC-610 Karl Fischer Moisture Titrators can store the results of up to 300 titrations on an USB flash drive (memory stick, AT-610, MKA-610 and MKC-610 only) or a compact flash card. The results stored on the memory stick or compact flash card contain all the relevant data, such as calculated results, titration curves, operator names, sample and measuring parameters.
  • With the Tview6 software the results stored on the memory stick or compact flash card can be archived, evaluated, printed out exported to other PC programs like Microsoft Excel, Access or Word.

Tview6 offers numerous possibilities to archive, evaluate and print the titration data:

  • Based on the titration curve data the endpoints can be reevaluated: The Tview6 software allows to simulate the endpoint detection of titration curves obtained with an AT-610 titrator and is thus a valuable tool to develop and optimize titration methods for difficult applications.
  • If required, results can be recalculated based on modified calculation formulas, constants, sample sizes, etc.
  • The filters and statistical functions of Tview6 make it easy to keep an overview of the results and to analyse them statistically.
  • The curves of several titrations can be superimposed.
  • Results can be printed out in freely definable formats based on customizable Microsoft Word templates.
  • The results can be exported to database and spreadsheet programs.
