Troubleshooting Chlorine Issues in Pools: A Guide for Calibrating and Adjusting Redox Probes

Client: Hello, I have a liquid chlorine dispenser with a probe. I calibrated it in the 470mv solution and adjusted it between 650 and 750mv. The chlorine level in the pool is much lower than it should be. I can't go above 800mv with my device. What should I do? I should mention that my pH pump is set to 7. Do you have a solution? Thank you
