My Pool Pilot works great, but it would be even better if it could measure the concentration of free chlorine in the pool and adjust itself correspondingly.

Upon browsing the internet I noticed that there exist several free chlorine sensors on the market. Are these prohibitively expensive or could they be added to a system such as the Pool Pilot so that I don't have to worry about the chlorine level setting any more?

To me this would be worth $300 to $400. It would be more useful than the automatic pH compensation, because the pH doesn't change as fast in my pool

I wonder if PoolSean has any information on this.

Thanks!
