How to test for salinity

Salinity is measured using a salinity meter placed in water. Water temperature influences salinity, so remember to record that too!

  • Turn on using the top button.
  • Use your sample cup (and reacher stick) to take a sample 15 cm + below the surface.
  • Immediately put your salinity meter into the water sample. Leave it there until temperature and salinity remain steady.
  • Read values. Top: salinity in ppt (parts per thousand). If there is a decimal, it is ppm (parts per million). Bottom: temperature in Celsius (°C).
  • Turn off the device to preserve battery life using the top button.
