pH Flow Control 5000

Continuous monitoring of pH

pH-EC Flow Control 5000 allows simultaneous, continuous monitoring of pH, conductivity (indication as EC and TDS) and temperature of solutions.

Based on the latest microprocessor technology, the instrument is completely developed and manufactured by STEP Systems in Germany.

The automatic sensor and buffer recognition makes operating errors and misstatements almost impossible – safety of correct application has been perfected.

Inverse indication of measured values when exceeding or dropping below the individually set limits ensures timely intervention in case of failures. The risk of over-fertilization or under-supply of plants by incorrectly adjusted fertilizer mixing systems is minimized.

With an additional relay card (version with relay output), external warning systems like bells, signal lamps etc. can be connected to the integrated outputs or corresponding switching functions can be carried out.

Owing to suspencion eye the unit can easily be wall-mounted and the optional tube-fitting kit enables an easy and fast installation and deinstallation of the probes (e.g. in case calibration or replacement).

Menu languages: German, English, Russian (optional).
