Salinity sensor

The Salinity sensor ML66m measures the salinity of a solution in the range from 0 to 50 ppt. The Salinity sensor consists of a Salinity electrode and an amplifier. Salinity is the measure of all the salts dissolved in water. Salinity is often expressed as parts per thousand (ppt), which is approximately equal to grams of salt per liter of solution. The average ocean salinity is 35 ppt and the average river water salinity is 0.5 ppt or less.

The Salinity sensor can be used in the following experiments:
• Measurements of salinity of water sources.
• Measure the change in salinity of saltwater as the water evaporates.
• Monitor the rate of reaction in a chemical reaction, in which dissolved salt-ions and solution conductivity vary with time, due to an ionic species being consumed or produced.

The Salinity sensor ML66m is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.

Technical specifications of the sensor are described in its User's guide.
