Calibration fluid redox 468 mV for chlorine measuring probe - 50 ml

A redox probe gives an indication of the oxidation power (and therefore chlorine content) of pool water. The higher the redox, the higher the oxidation power. It is necessary to calibrate the redox a few times a year against a 468mV buffer. If stored at room temperature and away from light, this liquid can be used for 2 years. In some cases (no bypass available), it is necessary to seal the electrode hole during calibration. You can purchase a fake probe for this purpose. Note: The Redox is not an absolute chlorine measurement, and the ideal redox is different for every pool. You should adjust the chlorine content to 1 ppm free chlorine using a reliable colour measurement. The Redox value you measure at pH 7.2-7.6 and at 1 ppm is the ideal set point for your pool. In most cases, this is between 600 and 800 mV.
