电导测盐法已被作为公认的方法,正式取代了克纽森滴定法。 近年来,虽已出现了多种型号的现场盐度计,然而都远不及实验室盐度计精确。在现场盐度计中,由于温度测量部分或温度补偿部分的时间常数很难和电导率测量部分一致,因而在温度分布不均匀的海区,往往在记录中出现一些虚假的跃变,在使用过程中,也不易进行校正。因此,实验室海水电导盐度计,目前仍被认为是精密测定海水盐度的标准仪器。 Electric conductivity salt method has been accepted as a method that officially replaced the Knudsen titration. In recent years, although many types of on-site salinity meters have appeared, they are far less accurate than laboratory salinometers. In the field salinity meter, the time constant of the temperature measuring part or the temperature compensating part is hard to be consistent with the conductivity measuring part. Therefore, in the uneven temperature distribution, some false jumps often occur in the recording. During the using process In the correction is not easy. Therefore, the laboratory seawater conductivity salinity meter, is still considered to be a standard instrument for the precise determination of seawater salinity.
