With optional functions for night deactivation of pH regulation, the six week calibration reminder and the visual pH alarm.
The pH controller is equipped with a BNC socket for connecting commercially available pH electrodes. The activity of a connected solenoid valve is indicated by an LED lamp. When switching into programming mode, the slot for the solenoid valve is deactivated for safety reasons. To protect the electronic components, a delay of 60 seconds is set between two switching states before the slot becomes active again. Break or short-circuit of a connected pH electrode are indicated as faults.
