I am currently servicing a Polaris Watermatic system and we have had ongoing problems with the ORP sensor reading. The unit is installed on a hot tub in a commerical application, approximately 3000 litres or so, and is connected to a bromine puck feeder. The system is 1-2 years old.
Initially both ORP and PH sensors were not working correctly. After much difficulty acquiring the parts from Polaris, we replaced both sensors. The PH sensor is now working fine, however the ORP sensor reading 660-700 and there is no Bromine in the hot tub.
Has anyone had similar issues with this system? Are there better systems available? If so what would you recommend.
Thanks for any help.
