Learn pH measurement by operating the instrument. Inspect the combination electrode, use fresh buffer aliquots, rinse without cross-contamination, apply gentle uniform stirring, perform a two-point calibration, review slope and offset, measure a fictional pharmaceutical sample, record pH with temperature and troubleshoot common electrode and handling problems.
Complete and finalize a measurement to generate the report.

A calibrated potentiometric system converts the electrode potential into a pH value using known reference buffers. The quality of the result depends on the electrode response, calibration range, temperature, stable response and contamination control.
