Place the salinometer in the calibration standard and mark the level where it floats. 6. Interpolate/extrapolate from the two marks you have made to add additional lines on the scale. You can calibrate your device using additional standards at other concentrations to improve its accuracy.

How do you make a Salinometer accurate?

Fill the container with water. Carefully insert the straw (clay covered end down) and add/remove clay until the straw floats at the maximum depth you wish. 3. Use the permanent marker to mark the depth where the salinometer floats in the water (0% salt solution).

How is Salinometer measured?

The Salinometer measures and supervises the salinity of fresh water produced by distillation of seawater. The salinity is measured in “parts per million”(ppm). The electrode unit measures the conductive and this value is equal to a certain no. of ppm.
