Product news
WTW’s new highly variable ionic sensor VARiON allows:
- The continuous measurement of ammonium – with on-line compensation for the interference ion potassium – via the ion-selective potassium electrode or
- On-line compensation of nitrate measurement – chloride as interference ion
- The third available slot can be used for an additional measuring electrode – this allows to measure ammonium and nitrate with one sensor (2 in 1)
All in all the following ready to start sets are available:
Ammonium measurement, compensated
Nitrate measurement, compensated
Ammonium measurement, compensated, with additional nitrate measurement
Nitrate measurement, compensated, with additional ammonium measurement
The advantages of the new VARiON system are obvious:
This combination sensor can measure both Ammonium AND Nitrate at the same time directly in the process. Due to its low investment and operating costs, it is a highly cost-effective solution for a reliable measurement 24 hours a day.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.

Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.
