Description
The KL-203 digital pH and oxidation-reduction controller is equipped with a 4-digit LED digital display. It can monitor and control pH value and ORP value in water for a long term. It runs on AC power with optional voltage from 110V to 240V. Two versions are available: test-only model, and test & control integrated model. This instrument continuously detects pH value in aquariums and other water systems. When the pH reading goes above or below the preset value, it will automatically turn on power to drive external devices, for example, activating the CO₂ solenoid valve to supply carbon dioxide.
