The Ph's maintenance fluid is extremely important for any tester. If the electrode is dirty or dry it will affect the reading accuracy.

Manufacturer Tip:
Testers are tools that need to be cleaned and calibrated regularly to extend their life.

Every tester needs maintenance, service and technical inspection, even if it is not broken. This process is called Calibration. When calibrated correctly it increases productivity, ensures consistency, comparability and compatibility with testers.
