The C800 Pro is a smart and flexible controller designed to measure and automatically adjust pH and EC levels in the batch tank of irrigation and hydroponic systems. It is specifically developed for horticulture, hydroponics, and professional cultivation systems where precise nutrient control is essential.

The C800 continuously measures pH, EC, PPM, TDS, and temperature, and automatically doses the set amounts per pump when values deviate from the target range. The controller features two separate UTP output ports:

• One for connecting a single pH dosing pump (to raise or lower pH)
• One for connecting 1 to 5 EC dosing pumps for nutrient dosing

This modular setup allows the C800 to function as:

• A combined pH and EC controller
• A standalone pH controller
• A standalone EC controller
• The system can be operated via the intuitive color touchscreen, which displays real-time values, alarm status, and historical data. For additional functionality, the C800 connects to the free Aqua Master Tools app(iOS/Android), giving you:
• The ability to store nutrient dosing schedules in the cloud and reuse them later
• Instant alarm notifications directly to your smartphone
• Access to real-time and historical graphs
• Remote adjustment of all dosing settings, set points, alarms, and calibration reminders
• Remote management of multiple devices from one app
• Both the controller and the app allow you to view up to 12 months of historical measurements and alarms, giving you full insight and control over your system at all times.
