2.1 Design and Function
Stratos Multi is designed as follows:
• The 1- and 2-channel transmitter permits a free combination of the pH/ORP process variables,
conductivity (2-/4-electrode sensors, toroidal sensors), and oxygen, and can, for example,
simultaneously measure pH values and conductivity.
• The device has four current outputs (active/passive).
• Add-on product options can be enabled by entering a transaction number (TAN).
• The color TFT display has white backlighting and provides clear information on errors during
parameter setting or measurement in accordance with NAMUR recommendations.
• The user interface is multi-lingual with full-text menu navigation presently available in
the following languages: German, English, French, Italian, Spanish, Portuguese, and Chinese.
