1 mL
for {volume} L reservoir
pH difference: 1 | Buffer factor: 1x
Usage Tips
- Add in small increments (0.5 mL per 10L), measure, repeat.
- Check pH after mixing thoroughly — EC and temperature affect readings.
- For hard water (high buffer), consider using RO water for better control.
- Calibrate your pH meter regularly for accurate measurements.
