Next to temperature and mass, pH is the third most common laboratory measurement. It crosses over many disciplines from water/wastewater analysis, basic research and development, environmental, chemical and life science, and an endless number of industrial applications.
To ensure quality results pH meters require frequent calibration against buffer solutions of certified pH value.
ROMIL PrimAg®‑TpH pH buffer reference solutions are accredited to ISO 17034 and supplied with a Certificate of Calibration reporting the certified pH value and associated uncertainty.
