bluelab Guardian Monitor, pH/EC-Monitor, measuring range: 0.0-14.0 pH or 0-2500 TDS and 0-3500 ppm

The bluelab Guardian Monitor (bluelab permanent meter) is a device for constantly measuring temperature, EC and pH levels in nutrient solution so that these parameters cn be adjusted to an optimum setting in each growth phase.

In just one device the Guardian Monitor measures all three critical parameters for successful growth: pH, conductivity and temperature. The bluelab Guardian reliably helps to detect and maintain the best possible water levels. This innovative parameter meter helps to chart the complexity of how each parameter relies on the other for outstanding growth. A flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively.
