Dr. Urs Hartfelder offers insights on how to reduce or prevent pH measurement errors.

To watch this webinar, please contact Mettler Toledo at info@mt.com.

Instruments measuring pH offer fast and simple operation, but accuracy, reliability, and repeatability of results are subject to various sources of error like contamination, asymmetric measurement cell, membrane resistance, or ambient temperature.

pH measurements are often considered to be easy, fast and simple. However, when the sources of potential errors are understood in more detail, results can often be improved which can lead to increased accuracy, repeatability and reliability.

In this webinar presented by Dr. Urs Hartfelder, METTLER TOLEDO Product Manager, discussed how to increase the accuracy, repeatability, and reliability of your pH results by knowing the sources of commonly made pH measurement errors.

Key Topics Include:

  • Overall model to understand different influencing factors
  • Details of quantifiable and unquantifiable errors
  • Theoretical information about the cause of the errors
  • Method to improve your measurement accuracy for respective errors
  • Approach to prioritize improvements
