Understanding metrological traceability in hydrogen peroxide sensor calibration

Assessing Calibration Traceability Uncertainty
Life Science

Metrological traceability is an important part of measurement. One of the best ways to understand an instrument’s measurement performance is to assess its accuracy. The instrument should be calibrated against an SI-traceable reference to ensure the quality of measurement data. Quality data, in turn, provides reliable information for decision-making. It's important to understand that the more calibration steps there are between the SI reference unit and the instrument, the greater the measurement uncertainty.

In the application note (PDF) below: "Understanding Calibration Traceability" you will learn how to assess an instrument's traceability from its calibration certificate. Also, scroll down to view authors' bios.

I am making a proposal for bio remediation of crude oil contaminated sites in Nigeria Delta of Nigeria.I need advice on the suitable instrument, parameters to monitor and quote to know the financial or cost implication.
