MultiLine® with IDS: A New Mobile

WTW GmbH have announced its new MultiLine® handhelds Multi 3410 and Multi 3430 with intelligent digital IDS sensors. The raw signals are directly converted by the sensor into digital signals which are insensitive against interference. The sensor logs on the meter with serial number and status information as calibration history

and specifications. Base of the sensors are the proven field tested and enhanced WTW pH and ORP sensors of the SenTix® family as well as conductivity cells of the TetraCon® and LR-series. Further advantages include: the new transmission technology allows any cable length particularly for pH sensors; the cables are rugged but flexible and have a better handling in comparison to the conventional ones. Currently cable lengths up to 25 m will be available.

The new IDS optical DO probe FDO® 925 with quick responding bevelled membrane and green light technology can be used in field and laboratory 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 has the ability of simultaneous measuring, displaying and storing of up to two, the Multi 3430 up to three parameters. Galvanically isolated sensor inputs allow simultaneous multi parameter measurement in the same sample without interference.

All meters have the same housing and keypad features as the ProfiLine handhelds. They are water proof (IP 67) and easy to clean. A new brilliant high resolution colour graphic display works as modern interface between user and meter. Of course all functions can be controlled by plaintext menus. The sensors will be recognised automatically. A memory for 10000 records allows long data collections in the field. The data can be transferred via an integrated USB host interface directly on a USB-Stick or selected printers. An additionally integrated mini USB interface is for connecting the MultiLine® handheld to a PC or laptop. A quick lock for the water proof sensor connectors provides a safe connection between sensor and meter. Rechargeable batteries which can be charged directly in the meter provide an economical operation. A choice of useful combinations of meters and sensors give the best possible application support.
