Typically salt water chlorine generators operate on a timed cycle. Part of the time they are making chlorine, then part of the time they are off and then repeat. The SmarterSpa and MegaChlor-CD are the only chlorine generators in existence with chlorine detection technology built into the electrode. We are often asked if our chlorine generators turn on when the chlorine is low and the answer has always been you need to adjust the power level and then measure the chlorine the next day so see if the chlorine is where you want it. Eliminates over-chlorination, no need for a vacation mode or temperature compensation and if you have the power level set too high it doesn’t really matter – chlorine generation the way you expect it to be!
The built in sensor is made out of the precious metal gold and copper. The controller measures for the presence of sanitizer as a small current that is developed between the two wires.
