应用
Potassium hydrogen phthalate standard reference material (SRM) is intended for use in preparing solutions for calibrating electrodes for pH measuring systems.
特点和优势
- SRM 185I is available with certified pH(S) values and their expanded uncertainties.
- Certified values are derived from potential measurements of cells without liquid junction by the primary measurement method.
- Certified values are metrologically traceable to the International System of Units (SI) of amount-of-substance and mass and to the definition of single ion activity.
- The NIST certificate is provided with maintenance, storage, handling, and use instructions.
其他说明
Please download a current certificate at nist.gov/SRM for current analytes and certified values.
