Industrial Transmitters Stratos Evo

Stratos Evo is the latest evolutionary stage of analyzers. The 4-wire multi-parameter device for measuring pH value, ORP, conductivity (conductive or inductive) or dissolved oxygen. The high-performance highPower broad-range power supply allows the operation with optical oxygen sensors.

The HighPower supply offers another advantage thanks to the option of also supplying external 2-wire transmitters, for example pressure or flow transmitters. The respective signal can be displayed and processed via the 4 … 20 mA input.


  • Comprehensive features and flexibility enable universal application.
  • One device for pH/ORP, conductivity or oxygen (configurable)
  • Operation of Memosens sensors
  • Interchangeable modules for operation with conventional analog sensors
  • HighPower supply for operating digital optical oxygen sensors
  • Power supply and signal processing for external 2-wire transmitters (pressure, temperature)
  • A multi-color backlit display signals operating states
  • Approved for Ex Zone 2 (IECEx, ATEX)
  • HART
  • Global use thanks to broad- range power supply
Sensor input, digital : Memosens pH or ORP sensors
Operating modes : AUTO – Calibration with automatic buffer recognition (Calimatic) : MAN – Manual calibration with the input of individual buffer values : DAT – Data entry of premeasured electrodes
Sensor monitor : Direct display of measured values from the sensor for validation
