Water/Wastewater MultiLine®
Multiparameter System from WTW WTW, a Xylem company, Germany, announces its new MultiLine®
handheld measuring instruments with IDS intelligent digital sensors. Proven sensors plus Intelligent Digital Sensor technology The new sensors are based on the proven WTW SenTix®
TetraCon® pH / ORP sensors and 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 previous ones too.
For optical D.O. measurement, a completely new IDS probe, the FDO® cap, thus making further calibration unnecessary.
Three meters for different applications
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.
Reader Reply Card No. 25 925 has been developed. It employs a factory-calibrated sensor
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.
The WQL data logger series from WTW can be used to monitor ground, surface, process and waste water. The slim design allows measurements at places that are difficult to access. Due to their robustness, protection class and temperature resistance, the loggers can also be used for extremely demanding applications.
Two logger types are available: WQL-pH for pH and ORP, WQL Cond for conductivity.
Long-term Measurements
New Optical Field D.O. Sensor: FDO® WTW, a Xylem company, proudly presents the optical field D.O. probe FDO®
intelligent digital sensors. The FDO®
925 is designed for use with the new MultiLine®
925 from WTW 925 belonging to the IDS family of
digital portable instruments and is suited for field as well as for
laboratory use (diameter 0.6” / 15.3 mm). With its extremely fast response (T99 < 60 s) and its bevelled membrane repelling air bubbles, it provides excellent signals for reliable measurements.
The new sensor relies on the technology of WTW’s proven on-line optical D.O. Sensor: Soft green light guarantees a long service life of the optical membrane. The exchangeable membrane cap bears a chip with factory calibration data which are read out by the MultiLine®
.
In combination with the new digital MultiLine® D.O. measurement.
portable instruments, the new FDO® 925 will re-define mobile Reader Reply Card No. 26
A powerful Lithium battery, intelligent power management and huge data storage capacity allows long-term measurements. Excellent Results
Meaningful measurements require a complete documentation. Hence the data logger works GLP compliant, independent and reliable. Reliable results are guaranteed by extremely stable and fouling resistant electrodes.
Fast Data Analysis
The PC software WQL-Log (free download) allows to produce graphical charts of your measurements with only a mouse click.
Perfectly Equipped
The practical case sets include comprehensive accessories and make the field use more convenient.
