In just one glance it magically measures all 3 critical parameters for successful growth; pH, conductivity AND temperature.

The Bluelab Guardian Monitor is a constant indicator of the desired levels of EC/ppm 700/TDS/CF, pH and temperature, enabling the grower to optimise these parameters as the crop progresses through each growing phase.

The Bluelab Guardian Monitor is mains powered and is mounted to the wall or hung on a support and the probes simply placed into the reservoir.

With the Bluelab Guardian Monitor monitoring your crops 24 hours a day and with the ability to set high and low alarms, a flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively.
