WTW inoLab Series for Multiparameter Measurement

WTW, a Xylem brand, has introduced two new members to the inoLab^® meter family for electrochemistry measurements: Multi 9420 and Multi 9430. These digital IDS meters are ideal for all laboratory applications including water, wastewater, environmental and water quality applications.

The inoLab Multi 9420 and Multi 9430 feature two and three universal sensor ports respectively, along with a large color graphic display and offer the latest advancement in “Plug and Measure” technology. The universal ports allow connection to the innovative, intelligent IDS sensors for measurement of pH, oxidation reduction potential (ORP), dissolved oxygen (DO) or conductivity. Each sensor contains model description, serial number, calibration history and unique sensor specific data including cell constants. Like other models in the inoLab meter series, these new multiparameter meters provide a range of unique advantages for users. The calibration process QSC (Quality Sensor Control) allows monitoring of the IDS pH electrode condition over its life span, while password protected user administration provides perfect traceability of all values. The instruments’ menu-controlled user interface allows easy, error-free operation and data can be transmitted for documentation via the USB interface or external printer.

The new inoLab models are ideal meters for use in laboratories where complete documentation is required such as quality assurance. The instruments offer the ability to automatically record pH, conductivity or dissolved oxygen data with the internal data logger in intervals as short as one second. Values can be stored or sent via the USB interface to a PC, while measurement data can be transferred in .CSV format for easy processing using spreadsheet programs. The new continuous measurement control (CMC) for pH allows the visual control in the correspondence between calibrated range and current measurement while the menu-driven user interface and the bright graphic display ensures ease of operation.

The WTW inoLab benchtop meter series supports error-free measurements and documentation by working with intelligent digital IDS sensors. Special firmware packages convert standard multiparameter instruments into meters for special tasks like ISE or other parameters. The former functionality can easily be restored at any time, while a special plug-in module offers unmatched versatility by allowing the connection of any conventional pH, ORP or ISE electrodes which enable the use of a broad selection of special electrodes. The inolab Multi 9420 and 9430 IDS meters together with IDS sensors are an ideal tool where documentation is required in water, wastewater, environmental and water quality applications.
