Measuring the Oceans Salinity - Density Makes the Difference
Measuring the Oceans Salinity - Density Makes the Difference
25 Mar 2016The salinity, and consequently the density, of seawater plays a crucial role in ocean currents. Instead of calculating the density from Practical Salinity, direct density measurement of seawater is gaining recognition among marine scientists. This application note demonstrates the measurement of ocean salinity using the DMA 5000 M.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.pH and Conductivity MetersIon and pH meters, used for electrochemical techniques and measurements, measure the concentration of specific ions using electrodes (probes) and a meter. Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.DensityWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.
