A salinometer is a device used to measure the amount of salt in a substance, providing a quick estimate of the dissolved salts in a water sample. It can be used in multiple scenarios such as agricultural water, drinking water, wastewater and home swimming pools. Salinometers typically measure salinity levels using conductivity, measured in Siemens (S), displayed as millisiemens mS/cm or microsiemens μS/cm. The software automatically generates estimated salinity measurements in parts per thousand (ppt), parts per million (ppm), grams per liter (g/L) or milligrams per liter (mg/L) based on conversion factors show. Salinometers are equipped with sensors and data processing devices to directly display the salinity content. When in use, clean the lens surface, drop in seawater, turn on the spotlight, observe the scale, and record the results.
A salinity meter typically measures salinity levels using conductivity, an assessment of the concentration of ions in a substance. You can calculate the amount of ions in a sample based on its ability to conduct electrical current in a specific area. The measurement involves conducting an electric current between two electrodes in the substance to be tested. The more ions there are, the higher the conductivity, and vice versa.
The salinity meter is equipped with sensors, measurement circuits and data processing devices, which can directly convert and process the measured data, and present the salinity content directly to the user, who can read the data directly on the panel.
Clean the refractometer lens surface. Use a dropper to draw about 2 to 3 ml of liquid and put it on the lens. Turn on the spotlight, drip seawater onto the eyepiece, and then gently cover the spotlight. Align the refractometer's focus plate toward the light source, keeping the eyepieces close to and parallel to your eyes. Observe the scale on the refractometer through the observation window and record the test value.
