What does annual calibration involve?
To fully demonstrate that all components of the pH measuring system are functioning correctly, the following steps should be performed: • Certified, traceable electrical simulators and standards should be used to verify that the pH meter is processing input signals correctly. • The performance of the temperature probes should be compared to a certified reference thermometer • The pH meter and electrode should be calibrated using certified, traceable pH buffers. • The correct performance of the pH electrode should be verified using certified, traceable control standards.For most pH users it is not practical to purchase and maintain a certified traceable pH simulator, as it is expensive. Reagecon’s Technical Services Department can provide a calibration service to customers that meets all their requirements, be it Instrument Calibration or Validation.
