Bromine Sensor

[Breixo]

Hi to all from Madrid,

I have an in-floor covered 8x4m pool. For the last 3 years I have been using bromine as a disinfectant (bromochloro-5,5-dimethylimidazoline-2,4-dione tablets) and sodium hypochlorite (common bleach 37gr/l) as an activator functioning without problems.

Now I want to automate the pool, my knowledge of chemistry was there, about 40 years ago, in the University, that is, I have no idea of Chemistry.

The first problem that I have found is the choice of a bromine sensor, please, can anyone guide me to acquire a good bromine sensor, minimum maintenance and permanent in-line operation?
