More product information
Guardian is an all-in-one monitor by Bluelab. With a simple glance at the LCD screen you'll know the values of the different parameters in real time. Submerge the probe in the nutrient solution tank and monitor the values of the main parameters immediately and with no interruptions.
It measures 24/24 h. It will provide you with readings of pH, Ec, TDS, PPM, CF and temperature. It has been specifically designed for indoor settings and can be mounted directly on the wall or on a support bar.
If one of the parameters' value falls too far from the appropriate range, the screen will start blinking to warn you about this anomaly.
It is calibrated at two different points with pH7 and pH4 liquids. It does not use any liquid for Ec.
