Hello, It's my 3rd summer with the device and the reading of my Star 20 Rx has become inconsistent. Despite the new calibration, the chlorine level is approximately displayed at 200 while on the test strip, it is fine. Do you think this is due to the probe or the device? Thank you
Hello
Test the probe like this: https://ph-redox-pool.com/gb/content/17-is-my-redox-probe-out-of-order
And then immerse the probe in the standard solution and read the value
Thank you, I will try and get back to you.
👍
Hello again, the system shows 132 and after adding salt, there is no change
It's the probe!
Okay, I will order one, can you please give me your reference number?
Thank you again. Best regards.
Have a great day
