pH measurement done right: The practical handbook for demanding lab environments

Drifting electrodes, unstable readings, uncertainty around buffer selection – pH measurement errors are rarely caused by faulty instruments. More often, they come down to gaps in the details. This free handbook delivers the hands-on knowledge that lab analysts, QA professionals, and process engineers need: from the electrochemistry behind the electrode to correct maintenance in daily practice – reviewed and updated drawing on over 80 years of measurement expertise.

pH measurement is one of the most frequently performed analytical procedures in the laboratory – and one of the most error-prone. Incorrect calibration, wrong buffer choice, or improper electrode storage: the causes are often small, but the impact on measurement reliability is significant.

The pH handbook closes these knowledge gaps – across 7 focused chapters:

Chapter 1 – Fundamentals: Potentiometry and pH measurement explained with clarity and precision
Chapter 2 – Electrode design: What's inside a pH electrode – and why it matters for your results
Chapter 3 – Electrochemistry of pH measurement: Understanding potentiometry to identify and prevent measurement errors
Chapter 4 – Buffer solutions & safety: Correct selection, proper handling, and safe application
Chapter 5 – Instruments & measurement setup: What really matters when configuring your system
Chapter 6 – pH measurement in practice: Real-world lab experience, not just theory
Chapter 7 – Maintenance & application guidance: How to care for your electrode and extend its service life

Who should download this handbook? Lab analysts and technicians who work with pH measurements daily – in water analysis, food and beverage, chemical, pharmaceutical, and research environments.
