Smart pH Controller

When pH fluctuates beyond the user-selected set point, the Smart pH Controller engages an LED display alarm to help growers precisely monitor pH levels. Unit features a 0-14.0 pH testing range, a set point range between 5.5 and 9.5 pH, and +/-0.2 accuracy. The controller comes with calibration solution and features a two-year warranty; a six-month warranty covers the included electrode.
