Maintaining proper pH levels is crucial in aquariums to keep fish and aquatic plants healthy. The pH controller ensures that the water remains balanced, promoting a thriving aquatic ecosystem. With temperature monitoring, you can also ensure the water conditions are perfect for your species.

The pH probe measures the reservoir's pH. The controller compares this to the desired pH and adds pH up/down solutions to adjust it. This ensures the nutrient solution's pH remains optimal for plant growth.

Display Comprehensive Data

The pH meter shows the current pH (7.5), desired pH (6.9), temperature (28.6°C), and potential sensor errors.

Ease of Use

You can screw it at the wall for your convience

Output for UP and DOWN Control

Ensures that your system can automatically adjust to maintain stable pH levels, promoting consistency and reliability.

Sensing Probe Measurement

High-precision pH sensing probe included with the pH controller is designed to deliver exceptionally accurate readings
