Field Instruments

General

The device is used for the conductive measurement/control of electrolytic conductivity, resistivity or the TDS value. In addition, the JUMO AQUIS 500 CR also offers the possibility of showing the measured conductivity according to a customer-specific table. Conductive two-electrode cells as well as four-electrode cells can be connected to the device. Temperature serves as the second input variable, measured by a Pt100/1000 probe. Depending on the measured variable, it is therefore possible to implement specific, automatic temperature compensation.

The device is operated using keys and a large LC graphics display on which the measurements are clearly legible. The plain-text presentation of the parameters makes it easier for the user to configure the device, and also helps in programming it correctly. Thanks to its modular design, the device can be perfectly matched to the particular application requirement. Up to four outputs are available (see the block diagram for the functions).

Typical areas of application

Universally applicable in water and wastewater engineering, service/process water and wastewater, drinking water and well/surface water, pure and high-purity water as well as for pharmaceutical water (e.g. as per USP, Ph.Eur., WFI), water quality  measurements, TDS measurements (ppm or mg/l).
