Troubleshooting Chlorine Reading Issues with the Star 20 Rx: Tips from a Technician

Client:
Hello, It's my 3rd summer with the device and the reading from my Star 20 Rx seems to have become inconsistent. Despite the new calibration, the chlorine level is displayed at around 200 while on the test strip, it is fine. Do you think this is due to the probe or the device? Thank you.

Technical Advisor:
Hello

Technical Advisor:
Test the probe like this: https://ph-redox-pool.com/gb/content/17-is-my-redox-probe-out-of-order

Technical Advisor:
And then dip the probe in the calibration solution and read the value.

Client:
Thank you, I will try and get back to you.

Technical Advisor:
👍

Client:
Hello again, the system shows 132 and after adding salt, there is no change.

Technical Advisor:
It's the probe!

Client:
Okay, I will order one. Can you give me your reference please?
