Dissolved oxygen and salinity are key factors when measuring the quality of water. As salinity increases, dissolved oxygen exponentially decreases. This is why saltwater holds 20% less dissolved oxygen than freshwater. A good example is dissolved oxygen levels near the equator; dissolved oxygen levels are lower at the equator because salinity and temperature are higher. […]

Conductivity probe cell constants determine the precise volume of liquid between two electrodes inside a probe. The cell constant (K) multiplies the measured electrical current (EC) to determine the electrical conductivity of the solution. The units of a cell constant are 1 per centimeter (1/cm); the number is a reference to the distance between the
