New Sensor Measurement Values for Ammonium and Nitrate by Compensating for Interferences from Potassium and Chloride

Ammonium and nitrate are key measurement values in sewage treatment plants. The ability to record and manage these parameters reliably plays a major role in efficient plant management.

The new AN-ISE sc sensor from HACH LANGE (Germany) means only one measurement needs to be taken. Ammonium and nitrate concentrations can be accurately recorded with real-time automatic compensation for potassium and chloride interferences by the ISE probe. With no sample preparation required beforehand, the parameters can be measured during the actual process, ensuring less interruption, reduced costs, time and maintenance thanks to the AN-ISE sc sensor.

The reason for easy and safe handling is the tried and tested CARTRICAL technology from HACH LANGE, which ensures the AN-ISE sc sensor is ready to use right away. Since all electrodes are perfectly calibrated with each other in the pre-calibrated cartridge, no time-consuming calibration is required for individual electrodes. The factory calibration is automatically implemented using the CARTRICAL plus system.
