Bluelab Guardian

The Bluelab Guardian continuously displays the desired values for EC, TDS, ppm 500 (KCl), ppm 700 (NaCl), pH, and temperature, allowing you to quickly and easily optimize them at every growth stage. The Guardian monitor operates on mains power and can be wall-mounted. The probes are simply placed in the desired container. The Guardian monitors your plants 24 hours a day. You can set high and low values, so the flashing screen alerts you to any deviation from the ideal value, enabling you to respond quickly and efficiently.
