MultiLine Meters with IDS Sensors: A New Mobile Multiparameter System WTW GmbH(Germany) announce their new MultiLine range of handheld measuring instruments with IDS intelligent digital sensors.
The new sensors are based on the proven WTW SenTix pH / ORP sensors and TetraCon conductivity cells. However, the IDS sensors convert the raw signals into digital signals which are insensitive against interference and can be transferred over large distances, particularly with pH sensors. Currently cable lengths of up to 25 m are available, and the cables handle much smoother than the previous ones.
For optical D.O. measurement, a completely new IDS probe, the FDO 925has been developed. It employs a factory-calibrated sensor cap, thus making further calibration unnecessary. Each IDS sensor automatically logs on to the meter with its serial number and status information, e.g. calibration history and specifications. These data are used to calculate the measurement value. Three new meters are available: The Multi 3410 is a one-channel multi meter for users who measure different parameters only sequentially. The Multi 3420 can simultaneously measure, display and store two,
the Multi 3430 three parameters.
All meters have waterproof (IP 67) housings and keypads. A new, brilliant high resolution colour graphic display provides a modern user interface. A memory for 10000 records allows extended data collection in the field. The data can be transferred to a USB stick, printers PCs or laptop via two integrated USB interfaces.

New Laboratory Instruments for pH, Conductivity and D.O.
WTW (Germany) introduced the WTW inoLab benchtop meter series for electrochemistry measurements in general laboratory applications. A perfect combination of functionality and features to meet the challenges
customers face every day. Available in a variety of meter models:
Accurate measurements: The inoLab 7110 series for customers who measurepHor conductivity in routine general laboratory applications. Whether measuring in wastewater, environmental or water quality applications, these meters offer advanced features in a simple to use package.
Compliant documentation: The inoLab 7310 is a perfect meter for use in laboratories where complete documentation is required such as a quality assurance laboratories. Automatically record pH, conductivity or dissolved oxygen data with the internal data logger. Values can be stored or sent via the USB interface to a PC and transferred in CSV format for easy processing using spread sheet programs.
The 7310 series is also available with an optional built-in printer.
Securely traceable: The inolab Multi 9310 IDS offers the latest advancement in “Plug and Measure” technology. The universal single input for connecting the innovative, intelligent IDS sensors allows connection of the pH, ORP, dissolved oxygen (DO) or conductivity sensor. Each sensor carries model description, serial number, calibration history, sensor specific data like cell constants and much more – every data set is unique. The inolab 9310 Multi IDS together with IDS sensors is a perfect tool for quality assurance labs across all industries.
