BlueLab Guardian Meter

Bluelab Guardian is a pH, conductivity (EC) and temperature monitor for indoor and outdoor nutrient solutions. It allows you to know at all times the exact settings of these important parameters, both in the growth phase and in the flowering phase of your plants.

Bluelab Guardian is on call 24 hours a day, and also has a configurable alarm system that lets you know instantly of any deviation from the ideal settings. The pH meter is submersible, and overall the monitor is very handy thanks to its small dimensions (153x24mm in diameter).

Bluelab Guardian has been specially designed for use in indoor cultivation. To mount it, just hang it on the wall or on a support bar and it is ready to use. With the alarm system you will be able to know when the solution deviates from the ideal parameters and correct it immediately, thus ensuring a higher probability of success in your crop.
