Saga Ph Controller for Aquariums

The Saga pH Controller is an automated device used in aquariums to monitor and regulate pH levels, typically by controlling the injection of  𝐶𝑂2 . It is designed for both freshwater and marine setups to maintain a stable environment for fish and plants. 

Key Specifications 

• pH Range: Measures 0–14 pH and controls between 3.0–11.0 pH.
• Display: Features a 0.56-inch large LED display for real-time readings.
• Resolution & Accuracy: Provides a resolution of 0.01 or 0.1 pH with an accuracy of ±(0.1% + 2 digits).
• Power: Operates on AC 110V–240V (50/60Hz).
• Output: Includes a relay contact (5A/240 VAC) with a Hi/Lo select function to trigger external equipment like solenoid valves.

Components and Maintenance 

• Electrodes: Probes (pH electrodes) are often sold separately but are required for the unit to function. These probes use a standard BNC connector.
• Calibration: Requires manual calibration using pH 7.0 and pH 4.0 (or 10.0) buffer solutions to ensure accuracy.
• Integration: Commonly used with a Saga Solenoid or CO2 Regulator to automate 𝐶𝑂2 delivery.

Cleaning instructions of the Saga pH Controller or Probe:

1. Clean the electrodes, please unplug, turn off the power.

2.PH electrode placed in water, can not exceed the height of the electrode cap regularly within a month with a soft brush to clean, when not in use, please put electrodes are placed inside the envelope there is the storage solution, if crystallization are normal phenomenon.

3.PH electrode is a precision glass products, do not knock.

4. Keep hands, cloth and other items alcohol wipe PH electrode.

5. This product is for indoor use only.

*Please note, that the controller controls the electrode. Both are needed to measure pH.
