What is a salinity meter?
A salinity meter is a device used to measure the salt content material in a substance. It is an easy-to-use water quality indicator tool and is an efficient method to shortly estimate dissolved salt in varied water samples.
They can be utilized for a extensive range of purposes, together with testing salinity levels in agricultural water, drinking water, and wastewater, as nicely as testing water in home swimming swimming pools and spas.
You can buy the salinity meter individually or use it as a sensor in a multi-parameter meter for measuring other water quality parameters, corresponding to pH, conductivity, TDS , chlorine, etc.
Working principle of salinity meter
The commonest method of measuring salinity ranges is through conductivity. Conductivity is a measure of the focus of ions current in a substance or sample.
You can calculate the ions current in a sample by the flexibility of the substance to switch current within an outlined area. The measurement involves the transfer of current between two electrodes immersed within the substance you need to test. The extra ions current, the higher the conductivity of the substance and the higher the conductivity reading, and the fewer ions current, the much 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 program of the salinity meter will generate a salinity measurement from the conductivity reading by mechanically applying a conversion issue. This issue is often 0.5; nonetheless, verify the precise conversion factor used for the device specs. The conversion factor will take the conductivity measurement and convert it to an estimated salinity measurement in parts per thousand (ppt), elements per million (ppm), grams per liter (g/L), or milligrams per liter (mg) display/L). For an in depth description of salinity parameters, see what is salinity.
How to learn salinity meter?
Salinity meters (also known as salinometers) are geared up with sensors, measurement circuits and data processing devices that may directly convert and process the measured data, allowing the salinity content material to be offered directly to the consumer, who can learn the information instantly from the panel.
How to make use of salinity meter?
Clean the lens floor of the refractometer.
Use dropper to soak up a drop of about 2~3cc of seawater within the seawater cylinder.
Open the spotlight, and drop seawater onto the target lens, and then gently cowl the highlight.
Point the focusing plate of the refractometer towards the sunshine supply, and hold the eyepiece near your eye and parallel.
Observe the scale on the refractometer by way of the viewing window and record the sea water.

Working principle of salinity meter
The most typical method of measuring salinity levels is through conductivity. Conductivity is a measure of the focus of ions present in a substance or sample.
You can calculate the ions current in a pattern by the flexibility of the substance to transfer present within an outlined area. The measurement entails the switch of current between two electrodes immersed within the substance you need to take a look at. The more ions present, 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 is called Siemens (S). Units are displayed in milliSiemens per centimeter mS/cm or microSiemens per centimeter μS/cm.
The software program of the salinity meter will generate a salinity measurement from the conductivity studying by automatically applying a conversion factor. This issue is usually zero.5; however, check the precise conversion issue used for the system specs. The conversion factor will take the conductivity measurement and convert it to an estimated salinity measurement in parts per thousand (ppt), elements per million (ppm), grams per liter (g/L), or milligrams per liter (mg) display/L).
