What is a salinity meter?
A salinity meter is a tool used to measure the salt content in a substance. It is an easy-to-use water quality indicator device and is an effective method to quickly estimate dissolved salt in varied water samples.
They can be used for a broad range of purposes, including testing salinity ranges in agricultural water, ingesting water, and wastewater, as properly as testing water in home swimming pools and spas.
You should purchase the salinity meter individually or use it as a sensor in a multi-parameter meter for measuring other water high quality parameters, corresponding to pH, conductivity, TDS , chlorine, and so on.
Working principle of salinity meter
The most common method of measuring salinity ranges is thru conductivity. Conductivity is a measure of the focus of ions present in a substance or sample.
You can calculate the ions present in a pattern by the ability of the substance to switch present within an outlined space. diaphragm seal includes the switch of present between two electrodes immersed within the substance you wish to check. The more ions current, the upper the conductivity of the substance and the higher the conductivity reading, and the fewer ions current, the less conductive the substance is.
The unit of measurement of conductivity known as Siemens (S). Units are displayed in milliSiemens per centimeter mS/cm or microSiemens per centimeter μS/cm.
The software of the salinity meter will generate a salinity measurement from the conductivity studying by automatically making use of a conversion factor. This factor is often 0.5; however, verify the specific conversion factor used for the system specs. The conversion issue will take the conductivity measurement and convert it to an estimated salinity measurement in components per thousand (ppt), parts per million (ppm), grams per liter (g/L), or milligrams per liter (mg) display/L). For a detailed description of salinity parameters, see what is salinity.
How to learn salinity meter?
Salinity meters (also known as salinometers) are outfitted with sensors, measurement circuits and knowledge processing devices that may instantly convert and process the measured knowledge, permitting the salinity content material to be offered directly to the person, who can learn the info immediately from the panel.
How to use salinity meter?
Clean the lens surface of the refractometer.
Use dropper to absorb a drop of about 2~3cc of seawater in the seawater cylinder.
Open the spotlight, and drop seawater onto the objective lens, after which gently cover the spotlight.
Point the focusing plate of the refractometer in path of the light source, and hold the eyepiece near your eye and parallel.
Observe the dimensions on the refractometer via the viewing window and report the sea water.

Working precept of salinity meter
The most common technique of measuring salinity ranges is through conductivity. Conductivity is a measure of the concentration of ions present in a substance or sample.
You can calculate the ions present in a sample by the flexibility of the substance to switch current within an outlined space. The measurement includes the switch of present between two electrodes immersed in the substance you wish to test. The more ions current, the upper the conductivity of the substance and the upper the conductivity reading, and the less ions present, the less conductive the substance is.
The unit of measurement of conductivity known as Siemens (S). Units are displayed in milliSiemens per centimeter mS/cm or microSiemens per centimeter μS/cm.
The software of the salinity meter will generate a salinity measurement from the conductivity reading by mechanically making use of a conversion issue. This issue is usually zero.5; nonetheless, verify the precise conversion factor used for the system specs. The conversion issue will take the conductivity measurement and convert it to an estimated salinity measurement in components per thousand (ppt), components per million (ppm), grams per liter (g/L), or milligrams per liter (mg) display/L). For a detailed description of salinity parameters, see what’s salinity.
