Hobby pH Control ECO - pH controller with visual alarm - delivery without electrode

With optional functions for night-time switching of the pH control, for the six-weekly calibration reminder and a visual pH alarm. The pH controller is fitted with a BNC bus for connecting commercially available pH electrodes. The activity of a connected solenoid valve is indicated with an LED light. When switching to programming mode, the insertion point for the solenoid valve is switched off for safety. To protect the electronic components, a delay of 60 seconds has been set between 2 switching states before the insertion point becomes active again. A break or short circuit of a connected pH electrode is displayed as an error.
