- Immerse the probe in the water sample.
- Gently stir and wait a few seconds for the reading to stabilize.
- Read the TDS value displayed in ppm.
- Rinse the probe with clean water after use and replace the cap.
Maintenance
For accurate long-term performance:
- Rinse the probe with clean water after each use.
- Do not immerse the meter beyond the maximum immersion line.
- Store dry inside the included black case.
- Replace batteries when the display becomes dim or unstable.
- Periodically verify accuracy using a calibration solution if precision testing is required.
💡 A TDS meter is one of the quickest ways to confirm that a reverse osmosis system is producing low-TDS water and that filters and membranes are performing properly.
