WebbIn the experiment, six sensors with different diameters are fabricated to realize the concentration of sodium nitrate sensing in seawater. By optimizing the parameters of sensor, the maximum sensitivity and detection limit of sodium nitrate in seawater can reach to be 5.98 pm/ppm (refractive index sensitivity is 50396.09 nm/RIU) and 0.17 … WebbSalinity sensors are used to measure the salinity of liquids and solutions and are capable of measuring the entire range from 24 to 52,000 ppm (parts per million). Salinity is the sum of all non-carbonate salts dissolved in water and is usually expressed in parts per thousand (1 ppm = 1000 mg/L). Salinity is an important measurement in seawater.
