Scope
This calibration system table is applicable to the value transfer of electrolyte solution conductivity measuring instruments. It stipulates the methods and procedures for accurately and reliably transmitting the conductivity value from the measurement benchmark to the working measuring instrument through the measurement standard. It describes the conductivity measurement benchmark, measurement Measuring ranges and metrological characteristics of standard and working measuring instruments. When performing calibration, it can also be used as the basis for traceability of value. In this calibration system table, conductivity refers specifically to the conductivity of electrolyte solution.
