pH-EC Flow Control 5000 Description：

operation manual

The pH-EC Flow Control 5000 enables simultaneous, continuous monitoring of the pH value, conductivity (in EC and TDS) and temperature of solutions. The device was developed based on the latest microprocessor technology from STEP Systems and is manufactured entirely in Germany.

Thanks to the automatic sensor and buffer recognition, incorrect conditions and incorrect information are virtually impossible - the security of the correct application has been perfected. Inverse display of measured values when the individually adjustable limit values are exceeded or fallen below ensures timely intervention in the event of malfunctions. The risk of over-fertilization or under-supply of plants due to incorrectly adjusted fertilizer mixture systems is minimized.

With the help of an additional relay card with an integrated output, external warning devices such as bells, flashing lights, etc. can be connected; alternatively, a corresponding switching function can be carried out.

The temperature, pH, conductivity and TDS values are shown on the display at the same time. The hanging loop for wall mounting allows for quick and easy installation. With the installation kit, the electrodes can be inserted and removed again directly into the line system or via a bypass without much effort (e.g. during calibration or electrode replacement).
