Digital communication
One Device for pH, ORP, Conductivity and Oxygen
The 4-wire multi-parameter device for measuring pH values, ORP, conductivity (conductive or inductive) or dissolved oxygen has a particularly powerful HighPower broad-range power supply on board, allowing for the use of optical oxygen sensors in addition to analog and Memosens sensors.

Fully Digital Integration Avoids Interference
The fully digital Stratos Evo platform allows for interference-free processing of measurement signals which are already digitized in the sensor. If analog sensors are used, the device already performs fully automated parameter detection when the measurement module is connected.

Supply of External 2-Wire Transmitters
The HighPower power supply provides an additional advantage through the ability to also supply external 2-wire transmitters such as pressure or flow rate transmitters. The respective signal can be looped through the 4 … 20 mA input and displayed.
