8 PROBE CARE AND MAINTENANCE
Keep the Conductivity/TDS probe clean. Rinse the probe twice, and gently swirl it while you
take readings. For best accuracy, soak a dry probe for at least 5 to 10 minutes or longer
before calibration. Rinse probe with deionized or tap water before storing. Never scratch the
bands with a hard substance. Do not strike the probe against any hard surface.
Do not immerse the probe in oily solutions. Clean the electrode thoroughly by stirring it in a
mild detergent bath or isopropyl alcohol. Wipe the probe with a soft tissue paper. Rinse
thoroughly in tap water and then in deionized water. Recalibrate the meter after cleaning the
probe.
The conductivity probe (Order Part No. EC-CONSEN91W/ 35608-50) which is included with
your meter features a removable probe guard to make cleaning easy.
To remove probe guard:
1. Grip yellow probe guard and twist clockwise. The locking notch will release.
2. Slide probe guard off end of probe.
