A salinometer was an instrument designed to calculate the salinity content. It also have thermometer can test the temperature.
Below is instruction of how to use it:

1, Handle the salinometer with care.
2, Draw off a sample of liquid to be test into trial jar.
3, Gently lower the hydrometer into the liquid until it floats freely.
4, Spin the hydrometyer to eliminate any air bubbles clinging to the side, as if this is not done a false reading may be obtained.
5, When the hydrometer stop moving, and is not in contact with the siade or bottom of trial jar, take reading as show on the below sign. The number you read is the density of the liquid.
