Your pH Electrode

Pick the Right Tip Shape for Your Testing Needs.

Spherical

A spherical tip is the most common shape for a pH electrode due to its large surface area. BEST FOR: aqueous samples and general purpose.

Conical

A cone shape makes testing of semi-solids easy. BEST FOR: direct penetration into semi-solids, emulsions, soil, and slurries.

Flat Tip

The flat tip allows for the direct surface measurement of a sample. BEST FOR: flat surfaces, skin, leather, and paper.

Do You Have the Right pH Buffers?

An essential step in achieving accurate pH readings is proper calibration. How do you know when calibration is necessary or why your readings are off?

When performing a pH calibration it is important that the correct buffers are used. For example, if you want to measure something with a pH of 9 and you only calibrate your pH meter to a single point with pH 7 buffer you may not get the most accurate measurement. This is because pH measurements are most accurate when multiple calibration points are used to bracket (are above and below) the expected pH value.

We manufacture a wide range of buffer solutions for a variety of uses. Visit our blog to find out.

Monitoring Slope and Offset

Important calibration values to monitor include slope and offset. These numbers provide information on the probe’s overall condition.

Hanna Tip: We recommend that you don't let the offset exceed ±30 mV and the slope percentage stays between 85-105%.

If you have a bad offset, this could mean that you either have a clogged junction or that the probe requires cleaning. If this occurs, try soaking the probe in a cleaning solution and repeat the process of checking offset.

If your slope is bad, this could mean you have used expired or contaminated buffers. If this is the case, ensure that fresh buffers are used.

pH Testing Tips

Clean Regularly.

Depending on the nature of 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 the proper storage solution and be sure to fully cover the junction.
