Details
The Bluelab Guardian Monitor gives 24-hour continuous readings for pH, conductivity (EC/ppm 700/TDS/CF) and temperature of a nutrient solution.
Ensuring the correct levels are maintained is essential for a plant's growth and health. The unit features an alarm setting to notify you if your nutrient solution requires adjustment. The unit has been designed specifically for use indoors and for wall mounting. Ensure the solution maintains an ideal range by specifying your highs and lows in the alarm settings and then the alarm will discreetly flash to inform you - there isn't any noise.
