In the section below we answer the following questions:
How do you know if your pH probe is working?
How do you know if your pool's pH probe is broken?
Is my pH probe dead?
Is your pH probe faulty?
To check if your pH probe is working, you can:
  • Soak the probe in a glass of water;
  • Read the pH value;

If the pH value drops by 1 or 2 pH units, your sensor is most likely working.
