Prizma is a chlorine and pH dosage-programming unit that self-adjusts automatically with the help of the photo-colorimetric tests that it carries out three times a day, on an average.

Each of the tests using this method is accurate and regulates precisely the doses of the chlorine and pH corrector. 

It comes ready to install with a wall-mounted bracket and all the accessories needed for connection to the pipeline: input-output for water analysis, the two chlorine and pH injection nozzles and pipes. 

A pool water sample is added to each colorimetric developer, a patented optical analysis process then determines the free chlorine DPD1 content and the RED PHENOL developer determines its pH level. 

Prizma can also pilot a salt electrolysis generator or bromine dispenser ...
