THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are adding automated dosing because manual tank adjustments are inconsistent and leave your crop vulnerable to swings.
  • You are consolidating multiple monitoring tasks into one hub because the complexity of manual testing slows your workflow.

  • The modular port setup is a life saver since you can just run one pH pump if that is the only metric drifting daily.
  • We found the mobile app syncs up without the typical lag we see on cheaper cloud controllers.

  • Facility managers say the automated dosing stopped them from having to check tanks during their off-site hours.
  • Users who rely on the app alerts say they caught early pH spikes before any visual stress appeared on the plants.

Aqua Master Tools C800 Pro pH/EC Controller

Manually checking and correcting pH and EC every day doesn't scale, and a missed adjustment can stress an entire crop. The Aqua Master Tools C800 Pro automatically measures pH, EC, PPM, TDS, and temperature in your batch tank and doses set amounts the moment values drift from target, keeping irrigation and hydroponic systems dialed in without constant manual intervention. While the C800 Pro handles automation, many growers also use the Aqua Master Tools H600 Pro Handheld Meter for quick manual spot checks.

Two separate UTP output ports give the C800 Pro modular flexibility: one connects a single pH dosing pump, the other connects up to five EC dosing pumps. That means it can run as a combined pH and EC controller, a standalone pH controller, or a standalone EC controller, depending on what your setup needs. For larger facilities, you can extend the connection to your dosing pumps using the Aqua Master Tools UTP Cable for C800 Pro Controller - 15m.

A color touchscreen displays real-time values, alarm status, and historical data on the unit itself. Connect to the free Aqua Master Tools app (iOS/Android) and you also get cloud-stored dosing schedules, instant alarm notifications, remote adjustment of set points and calibration reminders, and management of multiple devices from a single app. Both the controller and app retain up to 12 months of measurement and alarm history for full visibility over your system.

Frequently Asked Questions

Do I need to buy dosing pumps separately?+

Yes, the modular dosing pumps are not included with the C800 Pro and must be purchased separately to complete your dosing setup. To ensure maximum accuracy, we recommend calibrating your unit using pH 7.00 calibration solution.

Can the C800 Pro run pH only or EC only?+

Yes, thanks to its two separate UTP ports, the C800 Pro can function as a combined pH/EC controller, a standalone pH controller, or a standalone EC controller. For smaller tasks where a controller isn't needed, the Aqua Master Tools P110 Pro Combo Pen is a convenient portable alternative.

How many EC dosing pumps can I connect?+

The EC output port supports 1 to 5 EC dosing pumps, giving you flexibility for multi-part nutrient dosing schedules.

What can I do with the Aqua Master Tools app?+

The free app lets you store dosing schedules in the cloud, get instant alarm notifications, view real-time and historical graphs, and remotely adjust set points across multiple devices.

How much history does the C800 Pro store?+

Both the controller and the app retain up to 12 months of measurements and alarm history, so you can review trends and troubleshoot over time. Proper probe maintenance with Aqua Master Tools Storage Solution KCl is key to maintaining this long-term data integrity.

What happens when an alarm is triggered?+

The C800 Pro stops dosing automatically when low or high pH, EC, or temperature alarms trigger, preventing overcorrection until the issue is resolved.

Is the controller waterproof?+

The controller housing is rated IP63, and the electrodes are rated IP67 waterproof, suitable for typical grow room conditions. For pressurized systems, the Industrial 6 Bar Inline EC / PPM / TDS / Temp Electrode is a compatible heavy-duty alternative.
