How to use
Mix your nutrients first, then dip the meter in and read the pH and solution temperature. Adjust with a little pH Down, stir and read again.
- Calibrate it weekly with pH buffer.
- Keep the probe moist with storage solution.
- When the probe wears out, buy the replacement probe rather than a whole new meter.
For feed strength, pair it with the Aqua Master E50 Pro. Our pH and EC meters guide explains what pH to aim for.
Questions
Can I replace just the probe?
Yes. The replacement probe is sold on its own, as an option on this page.
How often should I calibrate it?
Weekly. All measuring equipment should be calibrated every week to keep nutrient solution readings accurate.
