Head Gavrylkin Volodymyr Georgyiovych, Registration Date 17-11-2014 Organization State Enterprise "All-Ukrainian State Scientific and Production Centre for Standardization, Metrology Certification and Protection of Consumer" popup.description2 The basic metrological parameters that must be determined for two-channel measuring transducer for the differential electrodes based on pH-sensitive field-effect transistors, for determination of absolute or relative pH of aqueous solutions in the range of 4 to 10 and oriented for use in biochemical and biosensor measurements. A statistical treatment of the data obtained from the measurement of the value of current in series model resistive load at 10 values of the applied voltage in the range from 1 to 2 V at a fixed temperature environment using 4 types of independent standard measurement tools in comparison with similar data obtained from 4 -x test samples of secondary transducers that are certified. According to the obtained data sets defined method of assessment of the expanded uncertainty of the measurement result and methods of attestation "Metrology. Secondary measuring transducer for differential electrodes based on pH-sensitive field-effect transistors. Methods of attestation1159-36-14".
