PH-301 Digital pH Controller with HI LO Automatic Control

Maintain more consistent water conditions with continuous monitoring and automatic pH-based equipment control. The digital pH controller measures from 0.00 to 14.00 pH with 0.01 resolution, giving you clear information about acidity and alkalinity. Its aquarium pH controller features selectable HI/LO action that can activate compatible equipment when readings rise above or fall below your chosen set point. A replaceable electrode, digital display, and dual-point calibration make it practical for ongoing aquarium, pool, aquaculture, and water-system monitoring.
