What is a salinity meter?
A salinity meter is a device used to measure the salt content in a substance. It is an easy-to-use water quality indicator device and is an efficient approach to quickly estimate dissolved salt in various water samples.
They can be used for a broad range of purposes, together with testing salinity levels in agricultural water, ingesting water, and wastewater, in addition to testing water in residence swimming pools and spas.
You can purchase the salinity meter separately or use it as a sensor in a multi-parameter meter for measuring other water quality parameters, such as pH, conductivity, TDS , chlorine, and so forth.
Working principle of salinity meter
The commonest methodology of measuring salinity ranges is thru conductivity. Conductivity is a measure of the focus of ions present in a substance or pattern.
You can calculate the ions present in a sample by the ability of the substance to transfer present inside an outlined area. The measurement involves the transfer of current between two electrodes immersed in the substance you need to test. The more ions current, the upper the conductivity of the substance and the upper the conductivity reading, and the fewer ions present, 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 issue. This factor is usually 0.5; nonetheless, examine the particular conversion issue 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), elements 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.
How to learn salinity meter?
Salinity meters (also called salinometers) are geared up with sensors, measurement circuits and knowledge processing devices that can instantly convert and process the measured information, permitting the salinity content to be introduced on to the consumer, who can read the information instantly from the panel.
How to use 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.
ไดอะแฟรม ซีล , and drop seawater onto the objective lens, and then gently cover the highlight.
Point the focusing plate of the refractometer in course of the sunshine source, and maintain the eyepiece near your eye and parallel.
Observe the size on the refractometer by way of the viewing window and report the sea water.

They can be utilized for a variety of functions, together with testing salinity levels in agricultural water, drinking water, and wastewater, as nicely as testing water in home swimming swimming pools and spas.

Working principle of salinity meter
The most common methodology of measuring salinity levels is thru conductivity. Conductivity is a measure of the concentration of ions current in a substance or sample.
You can calculate the ions current in a sample by the ability of the substance to transfer current inside a defined space. The measurement involves the switch of current between two electrodes immersed within the substance you wish to take a look at. The extra ions present, 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 is 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 automatically making use of a conversion factor. This factor is often zero.5; nevertheless, verify the precise conversion factor used for the device specs. The conversion issue 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).
