Plastic Combi 5000 PH Flow Controller, Color : Maroon

Continuous monitoring of pH

The pH Flow Control 5000 is a solid flow meter for continuous pH measurement in pipeworks.

Based on the latest microprocessor technology, the instrument has completely been 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.

By exceeding or dropping below the freely adjustable limits:
• Version without relay output: inverse graphic indication
• Version with relay output: inverse graphic indication and possibility of alert system and/or control function for dosage pumps.

The tube-fitting kit enables easy and fast installation and de-installation of the probes (e.g. in case calibration or replacement).

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