A continuous for professional use, a clear and reliable measurement of the liquids.


Measured at a glance all 3 critical parameters for a successful harvest, these are: pH, EC, and temperature. The Bluelab Guardian Monitor is therefore a continuous meter for measuring the following values: EC / ppm 700 / TDS / CF, pH and temperature


The Bluelab Guardian Monitor can be hung on a wall or a support beam, the sensors must be placed in the reservoir.


The Guardian monitors your feed water (or the fluid to be measured) 24 hours a day and gives the option to set alarms for high and low values, with a flashing screen warning you if 1 of the values ​​deviates from the optimum value and you have the opportunity to make the desired corrections quickly and efficiently.
