KF756 Coulometer: The Ultimate Solution for Precise Water Content Determination

The Metrohm KF756 Coulometer is specially designed for determining low levels of water content. Despite its compact construction, this instrument meets all requirements, offering comprehensive features and unmatched precision.

The integrated printer and two RS 232C interfaces enable seamless communication with balances, external printers, and computers, thereby facilitating data management and production. The KF756 guarantees precise and reproducible results, even for water contents in the microgram range.

One of the highlights of the KF756 is its backlit graphical display. This screen not only provides a clear presentation of parameters but also graphically shows the progression of the KF determination in µg of water over time. This feature significantly aids in the evaluation of the determination process and is a great help in method development and validation.

For enhanced connectivity, the optional remote box allows for the connection of a barcode scanner and a PC keyboard to the KF756 Coulometer. This functionality increases the instrument's versatility and ease of use in various laboratory environments.

Compatibility with GLP and ISO 900X standards ensures that the KF756 is ready for modern laboratory requirements. Users can program GLP and ISO 900X functions such as service or validation intervals, alerting them in time for necessary tests. The GLP mode aids in instrument validation, containing formulas for calculating contents and recovery rates, thus enabling the assessment of systematic errors or biases.

The KF reagent can be monitored concerning the number of determinations carried out, its useful lifespan, drift value, or capacity. Whenever the reagent needs to be replaced, the instrument automatically issues a corresponding request. To avoid any mishaps, users can set limits for sample weight or volume and the result. If any quantity exceeds the defined limits, a warning message appears on the display and report, and the "Remote" interface emits a signal.

The KF756 Coulometer is flexible yet easy to use, solving the problem of complex instruments being difficult to operate. It offers both an expert mode and a standard mode, with the standard mode only providing access to functions needed for routine work, requiring very few keystrokes, and being extremely intuitive. The pre-stored user methods allow for immediate start of water determinations.

The instrument is available with two types of generator cells: a cell without a diaphragm, requiring only one reagent and being virtually maintenance-free, and a cell with a diaphragm, recommended for determining water in aldehydes and ketones, extremely low water contents, and samples with very low conductivity.

Different applications require different instrument settings, and the method memory of the KF756 Coulometer can hold about 100 methods. Additional methods can be transferred to a PC via the RS 232C interface using Metrodata VESUV software and recalled at any time.

The KF756 Coulometer by Metrohm is a versatile and reliable instrument designed for precise determination of low water content, making it an essential addition to any laboratory focused on accurate and reproducible results.
