Electrolysis systems on most pools are good but they also lack a measuring ability that allows to check if the current redox value of your pool is correct.
BoPi will test that value and adjust the on time of the electrolysis kit accordingly.
This will save money if it was running too much but most of all will make sure your salt pool doesn’t generate too much chlorine that could hurt some user’s skin or eyes.
BoPi is compatible with any electrolysis kit that works when powered.
