Display:

GAOTek water hardness meter is equipped with a clear and bright LCD display that is used to show measured values, mode indicators and help message. The following table describes the meaning of each indicator.

Electrode Care and Maintenance:

  • Ensure that the electrode is thoroughly washed with distilled water after each use.
  • DO NOT scratch the sensitive membrane on electrode during the measurement or calibration.
  • If performance becomes sluggish, rinse with dilute detergent, rinse with de-ionised water and immerse the tip in a 1000ppm calcium solution for 1 hour.

Troubleshooting:

LCD DISPLAY

CAUSE

CORRECTIVE ACTION

 —- Electrode dried out Soak the conductivity electrode in tap water for 10 minutes
Measured value is out of range Check the electrode whether dirty or broken
 Err Incorrect calibration solutions Using the fresh calibration solutions for calibration
Electrode is out of service life Replace the water hardness electrode
