Bluelab Guardian Monitor PH EC Temperature


With the professional Bluelab Guardian Monitor, you can monitor the pH, EC and temperature of your nutrient solution 24 hours a day.

This monitor offers you the possibility to set an alarm for each parameter with a minimum and maximum value. A flashing display lets you know if your parameters deviate from the optimum, so that you can immediately take action. Thanks to the large, clear display, the measurements are also visible from a distance.

The Bluelab Guardian Monitor works on mains power and can be hung on the wall as well as on a railing with the probes in your reservoir or nutrient solution.

Also useful: the pH electrode is replaceable, so you can continue to use this meter in the coming years. In addition, the conductivity / temperature sensor requires no calibration.
