4. How to use Etatron pH, ORP, and conductivity calibration solutions

To ensure maximum calibration accuracy, follow the manufacturer’s recommended handling and calibration procedures.

Basic steps:

Rinse the electrode thoroughly with deionized (DI) or distilled water and gently blot dry with a clean, lint-free tissue.
Pour a small volume of the calibration solution into a separate, clean sample cup.
Immerse the electrode into the solution and wait for the reading to stabilize.
Calibrate according to the reference value printed on the product label.
After calibration, rinse the electrode again with distilled water.

Important handling precautions:

Never submerge the electrode directly into the primary stock bottle.
Do not reuse spent calibration solutions.
Store solutions in a cool, dry place away from direct sunlight.
Perform scheduled routine calibrations to maintain instrument accuracy.
