摘要
海水电导率是表征海水导电能力的物理量。1978实用盐标的贯彻,使得利用海水电导率测量仪测定盐度法成为当前测量盐度的主要手段。由于使用环境的特殊性,海洋调查对海水电导率测量数据的可靠性提出了更高的要求,通过对电导率测量仪进行定期校准,可以保证海水电导率测量数据的准确性,维护盐度计量单位统一和量值准确可靠。文中详细介绍了海水电导率的校准原理、校准程序及校准结果的不确定度评定方法。
Seawater conductivity is the physical quantities characterizing seawater conductive ability.According to PSS78,conductivity measuring instrument has become the major mean of salinity measurement.For the seawater conductivity measuring instrument used in the special environment,marine survey puts forward higher requirements to reliability of seawater conductivity measurement data.The accuracy of measurement data could be ensured through calibration regularly,maintaining the salinity unit uniform and measurement value accurate.The calibration principle,procedure and uncertainty assessment method of calibration data for conductivity measuring instrument is introduced.
