MS-310
Micro-Salinometer

Improved Specification

±0.002 PSU

The MS-310 is based on a new concept in which the conductance of the sample is simultaneously compared with the conductance of a reference. Every sample is therefore standardized, and the standard itself is enclosed in glass to preserve the integrity of measurement for weeks. This dual cell innovation removes the need for highly stable bath temperatures, and the cells are surrounded by a well stirred oil bath to ensure thermal uniformity.

The MS-310 provides oceanographers with a reliable shipboard method to verify the performance of sophisticated modern CTD instruments.  By giving a direct measurement of R_T against the reference it gives a rapid confirmation of accuracy of a CTD with low operating costs. 

The instrument has been developed in collaboration with the Marine Hydrophysical Institute ( Ukraine ), and it complements laboratory salinometers.
