WTW IDS pH Electrode SenTix® 940

WTW IDS pH/ORP Electrodes

• Fail-safe measuring signal
• Calibration status in the electrode
• Proven reliability and accuracy

Interference-free measurements
The conversion of the measuring signal into an interferenceproof digital signal takes place directly in the electrode. This also means a pH measurement with long cables is now possible.

Calibration data in the sensor
The calibration data are stored in the electrode itself, transmitted to the meter and displayed. In addition to the proven CMC function for the visual presentation of the calibration point, the new QSC function provides a graphic assessment of the actual electrode quality for IDS pH electrodes.

Proven electrodes
The technology of the new IDS pH/ORP electrodes is built on the proven, high quality electrodes of the SenTix® and SensoLyt® series. Measurement and maintenance of the electrodes remain unchanged: the only difference is in the electrode head.

CMC function
The CMC function graphically supports the continuous monitoring of the measuring range. The measuring range is displayed as a graphic bar with the calibration points as vertical lines. Each calibration point includes a confidence range of ± 2 pH. A moving cursor shows the current measured value and indicates if the measurement range is within the range or whether the calibration should be adjusted to match the giving measuring requirements.

QSC function
QSC (Quality Sensor Control) is a system to monitor the condition of the IDS pH electrode. An initial calibration is performed and thereafter the sensor status is monitored over time. The result is displayed as a graphical symbol. For the MultiLine® and inoLab® Multi 9420/9430 IDS meters this is a green to red shaded bar, for the inoLab® Multi 9310 IDS it is a black and white scale element.

ADA S7/IDS
The ADA S7/IDS® connects special electrodes such as penetration, split ring or surface electrodes. The S7 plug head can be easily connected to a MultiLine® or inoLab® IDS instrument.
