pH Testing Tips

Clean Regularly.

Depending on the nature for your samples, your pH electrode can become dirty or clogged resulting in slow and faulty readings. Regular cleaning will prolong the life of your electrode.

Calibrate Often.

To ensure your pH measurements are accurate, be sure to calibrate after extended storage, cleaning, and before use. Use fresh buffers that bracket your expected value.

Condition Always.

A dry electrode results in slow, incorrect measurements. Always use proper storage solution and be sure to fully cover the junction.
