This BlueLab device measures all 3 critical parameters for successful plant cultivation. It measures the pH value, the conductivity and the temperature. It enables the grower to optimise the desired levels of EC, ppm 700, TDS, CF, pH and temperature parameters.
This Bluelab pH pen is a very handy pH-Meter, which measures pH-value and temperature. Hand held, with a range of 0-14 pH and with an accuracy of ± 0,1 pH.
