Blue Lab - Guardian Monitor
Bluelab Guardian Monitor
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.
