The Bluelab Guardian Monitor Wi-Fi provides continuous, accurate readings of your nutrient solution’s pH, EC, and temperature, giving growers total visibility into their system’s conditions at all times. Designed for precision hydroponic management, it eliminates the need for manual testing and ensures plants receive the optimal balance of nutrients.
With built-in Wi-Fi connectivity, growers can remotely view real-time readings and receive alerts via the Bluelab Edenic App for complete peace of mind. The bright, plant-safe LED display shows all three key parameters simultaneously, while adjustable high and low alarms provide instant feedback when readings move outside target ranges. Conductivity and temperature probes are factory-calibrated, and the pH probe is easily recalibrated for ongoing accuracy.
Built to last, the Guardian Monitor Wi-Fi operates from mains power with international plug options and can be wall-mounted or positioned conveniently near reservoirs. The previous non-Wi-Fi model has been discontinued; this updated version adds cloud connectivity for data access and improved grow management.
