Care & Maintenance
Please read the information below, to ensure the highest possible accuracy:
• Fresh buffer should be used for each calibration, once the sachets are opened
the buffer value can change over time.
• For improved accuracy a two-point calibration is recommended.
• If the electrode is slow or sluggish, soak it in cleaning solution for 20
minutes. Rinse with water and hydrate the electrode in storage solution for a
minimum of 30 minutes before calibrating.
• If measurements are taken successively, rinse the probe thoroughly in
distilled or deionized water to eliminate cross-contamination.
• When not in use, add a few drops of storage solution to the protective cap
to keep the glass tip and the junction hydrated. If storage solution is not
available, pH 4.01 or pH 7.01 buffer can be used. Never store the probe in
distilled or deionized water.
Note:
Never immerse the tester over the maximum immersion level.
Battery Replacement

the battery cover, located on the back of the tester,
counterclockwise to unlock. Remove cover and
replace the battery with positive (+) side facing out.
Note:
