The simplest and most effective reservoir monitor you could ever own!
The Bluelab Guardian Monitor provides 24 hour continuous reading for pH, conductivity (EC/ppm 700/TDS/CF) and temperature within a nutrient solution.
Optimizing these critical parameters through a plants growing phase helps ensure a successful crop.
Designed for indoor use, the Guardian Monitor can be mounted on a wall or hung on a support bar. Set up your reservoir, place the pH and conductivity probes in the solution, then adjust and glance!
Simply set high and low alarm states if the solution moves away from the ideal range, the display flashes. A quick look at the monitor will let you know when your nutrient solution needs adjusting.
