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.

Cleaning is the most important piece of maintenance required on any Bluelab instrument. The probe comes into contact with the solution and relay the reading back to the instrument for it to be displayed. The probe surface is susceptible to being contaminated or being covered in a greasy film that inhibits an exact reading. There are no shortcuts to cleaning the probes. It is already a very simple procedure and it will also ensure your instrument measures it right every time.
