NOA-INSTRUMENTS pH Controller 2in1 pH & Temperature

Control and display of the pH in aquaria.

Depending on the pH, the power supply for a consumer is switched.
This is usually a solenoid valve for controlling the CO₂ addition, but can of course also be a peristaltic pump for dosing DRAK pH/CH-Minus or similar.
