26 Water/Wastewater New Multiparameter Water Meter Launched


WTW, a Xylem (USA) brand, introduces the two newest 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 colour 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 perfect 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 a perfect tool where documentation is required in water, wastewater, environmental and water quality applications.

Aquaread Water Quality Testing Products


Aquaread, the UK’s leading designer and manufacturer of multiparameter water quality testing instruments, is launching a brand new range of sondes and electrodes. 12 brand new electrodes have been designed, comprising of both Ion Selective and Optical electrodes. These electrodes will be housed in the user configurable (Aux) ports of the new sondes.


First, the multiparameter AP-2000 which is designed to be portable. This sonde will feature Aquaread’s all new metal connectors and new extension lead system, a re-designed protective sleeve and most importantly more choice and more parameters. The AP-2000 will boast a set of standard parameters: Optical DO, EC, pH, ORP and Temperature, along with 2 Aux ports to house 1 ISE Electrode and 1 Optical Electrode, and the option to add a depth sensor. All of this is housed in under 2” diameter making it the slimmest and most feature packed multiparameter sonde available today.


Secondly, the self-cleaning multiparameter AP-7000, which is designed for fixed monitoring. This probe again features the all new Aquaread metal connectors and extension system, and offers the standard parameters mentioned above plus 6 Aux ports to house any combination of the 12 brand new sensors. This sonde is capable of monitoring at depths of up to 100m, it will also offer unrivalled customization options, a novel self-cleaning mechanism and a solid marine grade aluminium body with a diameter under 80mm.


Whether you require a portable system or an installed system Aquaread has the answer. Data can be collected either using the GPS Aquameter, one of our data loggers (AquaLogger series) or a telemetry system. The new sondes and the extended range of sensors including Ammonia, Nitrate, Chlorophyll and Refined Oils, makes Aquaread systems the perfect choice for monitoring water systems in your region.

New White Paper Shows How to


Maintain pH Sensors


Endress+Hauser (UK) introduces “pH Sensors: Know whether to calibrate the sensor, clean the sensor, perform a calibration check or ...?,“ a non-commercial white paper that outlines the proper procedures for maintaining and calibrating pH sensors.


All pH sensors in a process need to be inspected, cleaned and calibrated on a regular maintenance schedule to ensure accurate readings. In some companies, however, maintenance and quality control directives may not be specific enough when dealing with pH sensors.


For example, they may not describe the exact procedures involved in calibrating a pH sensor, or the proper timing for when to conduct pH calibration and maintenance. On the other hand, the instructions may be too specific, detailing many more procedures and operations than are actually required.


This non-commercial white paper describes; 'knowing when to do a pH sensor calibration versus a calibration check', 'how to properly clean a pH sensor' and 'how to perform a pH sensor calibration'.


The paper includes a complete decision tree diagram that shows, step by step and in great detail, the proper procedures and operations required to maintain pH sensors.
