IKS Aquastar Redox Module -Electronic Adapter, Electrode & Calibration Solution For IKS Aquastar Aquarium Automation System

You can continuously measure and regulate the redox 
potential of your aquarium with the help of this module.As the module is 
galvanically separated from the basis system, the redox potential can also be 
measured at different points within a single water circuit without the 
individual sensors having an effect on each other. You can choose between 
having the redox potential displayed on the iks aquastar in mV or as the 
rH-value.
