Aqualight pH Controller PH-201 with electrode

Aqualight pH Controller PH-201 with electrode

The PH-201 continuously measures and controls your pH-dependent devices – ideal for CO₂ solenoid valve control in freshwater or saltwater aquariums.

The switchable control direction (HI/LO) allows you to lower the pH (e.g., CO₂ addition) or raise it (e.g., limewater).

Two-point calibration (pH 7 and pH 4/9) ensures reliable values.

• Measuring range: 0.00–14.00 pH · Adjustment range: 3.50–10.50 pH · Resolution: 0.01 pH · Accuracy: ±0.1 pH.
• Control direction switchable (HI-A / LO-A) for pH reduction or increase; relay socket 5 A/240 V switches the connected device (e.g. solenoid valve).
• Calibration: pH 7 (CAL) + pH 4/9 (SLOPE) – quick and precise results.
• LED display (4-digit) , 230 V / 50 Hz , only 2 W power consumption. K
• Dimensions 150 × 85 × 42 mm
