Why pH meter is not working?
If the reference junction on the probe is not clean the probe may become unresponsive. Field Electrodes: Regularly soak the electrode in a 1:1 bleach water solution for 15-30 minutes to reduce the chances of a clogged reference junction. If hard deposits have built up on your probe (ie.
How long does a pH electrode last?
about one year
Current pH electrodes have a lifespan of about one year or up to 18 months at the most (with less frequent use). If you properly care for your electrodes, you’ll still need to replace them roughly annually. That said, there are things you can do to avoid damaging your pH electrodes.

How do I clean my bluelab conductivity pen?
For the Bluelab Truncheon, twist the shroud 90 degrees and remove. For all Bluelab conductivity probes and the Bluelab Commercial Truncheon, warm the shroud in your hand for a few seconds to help with removal. Hold the body and gently pull the shroud off.
What are the possible sources of error in the use of a pH meter?
The pH electrode is usually made of glass. Coatings on the glass surface can alter the pH readings significantly. Coatings of different substances, including pollutants, solids, biofilms, poorly soluble deposits, lime, or oils can make the glass surface inaccessible to the measured medium.

What is the most common error in pH measurement?
What is the error in a pH meter?
The pH measurement shows a higher pH value than the actual pH value of the measured liquid solution. This effect is known as the acid error. As with the alkaline error, manufacturers supply specialized measuring electrodes with glass membranes having specially low acid errors.
