  If you encounter a calibration error with your Apera Instruments Measuring Instruments, several factors could be the cause. First, ensure you're calibrating in the correct order: always pH 7 first, then pH 4 or pH 10. Also, check that your calibration standard solutions are fresh, clean, and from a reputable manufacturer. A contaminated electrode can also cause errors, so thoroughly clean it. An aged or dried-out electrode may also be the culprit; if aged, replace it, and if dried out, soak it in the soaking solution overnight. Ensure the electrode is fully immersed in the solution, above the junction, and that there are no air bubbles around the sensor. Finally, make sure to wait for the reading to fully stabilize before pressing to finish the calibration.

  Angela WardAug 11, 2025
  If the reading on your Apera Instruments Measuring Instruments is always slowly changing and won’t stabilize, it could be due to several reasons. The electrode might be contaminated, so thoroughly clean it. Another possibility is a clogged junction, which also requires thorough cleaning. An aged electrode can also cause this issue, so consider replacing it. If you're testing low ionic strength solutions like distilled or deionized water, this can also lead to unstable readings.

What to do if Apera Instruments PH60-MS is showing jumping readings?

  Todd JohnsonAug 16, 2025
  If your Apera Instruments Measuring Instruments is showing jumping readings (generating random numbers), there are a few potential causes. First, ensure the electrode is fully immersed in the solution, above the junction, and that the storage vial is removed. Air bubbles around the sensor can also cause this, so give the solution a quick stir. Finally, check the electrode's connector to ensure it's not broken and is correctly connected. When no electrode is connected, screw on the connector cap to protect the connector.

Why is Apera Instruments Measuring Instruments displaying similar readings in any solutions?
- M
  Marissa GrayAug 22, 2025
  If your Apera Instruments Measuring Instruments displays similar readings in any solution or is stuck at 7.00 pH, it could be due to a broken electrode. If you don’t see any physical damage of the electrode and it’s within the 6-month electrode warranty, contact us for warranty fulfillment; If there is visible damage, replace the electrode. Another possibility is an instrument defect; in this case, contact us for warranty fulfillment.
