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 efficient method to rapidly estimate dissolved salt in varied water samples.
They can be used for a variety of applications, including testing salinity ranges in agricultural water, ingesting water, and wastewater, as well as testing water in house swimming pools and spas.
You should purchase the salinity meter individually or use it as a sensor in a multi-parameter meter for measuring different water high quality parameters, similar to pH, conductivity, TDS , chlorine, etc.
Working precept of salinity meter
The commonest technique of measuring salinity levels is through conductivity. Conductivity is a measure of the focus of ions current in a substance or pattern.
เครื่องมือวัดความดัน can calculate the ions present in a sample by the flexibility of the substance to transfer present inside a defined space. The measurement involves the transfer of current between two electrodes immersed in the substance you need to check. The extra ions current, the higher the conductivity of the substance and the higher the conductivity reading, and the less ions present, the much less conductive the substance is.
The unit of measurement of conductivity is recognized 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 routinely making use of a conversion issue. This issue is typically zero.5; however, check the specific conversion factor used for the gadget 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). For an in depth description of salinity parameters, see what’s salinity.
How to read salinity meter?
Salinity meters (also called salinometers) are geared up with sensors, measurement circuits and knowledge processing units that may instantly convert and process the measured information, permitting the salinity content to be introduced directly to the consumer, who can read the information directly from the panel.
How to use salinity meter?
Clean the lens surface of the refractometer.
Use dropper to soak up a drop of about 2~3cc of seawater in the seawater cylinder.
Open the highlight, and drop seawater onto the objective lens, and then gently cover the spotlight.
Point the focusing plate of the refractometer in direction of the light source, and hold the eyepiece close to your eye and parallel.
Observe the dimensions on the refractometer by way of the viewing window and report the ocean water.

They can be utilized for a variety of functions, together with testing salinity levels in agricultural water, consuming water, and wastewater, in addition to testing water in house swimming swimming pools and spas.
You can purchase the salinity meter separately or use it as a sensor in a multi-parameter meter for measuring different water high quality parameters, such as pH, conductivity, TDS , chlorine, and so on.
Working precept of salinity meter
The commonest method of measuring salinity ranges is thru conductivity. Conductivity is a measure of the concentration of ions present in a substance or sample.
You can calculate the ions present in a pattern by the power of the substance to transfer current inside a defined space. The measurement includes the transfer of present between two electrodes immersed in the substance you need to check. The more ions current, the higher the conductivity of the substance and the upper the conductivity studying, and the fewer ions current, the much 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 reading by routinely making use of a conversion factor. This factor is often zero.5; nonetheless, examine the precise conversion issue used for the gadget specs. The conversion factor will take the conductivity measurement and convert it to an estimated salinity measurement in elements per thousand (ppt), elements per million (ppm), grams per liter (g/L), or milligrams per liter (mg) display/L).

Salinity meters (also referred to as salinometers) are equipped with sensors, measurement circuits and information processing gadgets that will directly convert and course of the measured knowledge, permitting the salinity content to be introduced directly to the person, who can learn the information immediately 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.
Open the spotlight, and drop seawater onto the target lens, after which gently cowl the highlight.
Point the focusing plate of the refractometer towards the sunshine source, and maintain the eyepiece close to your eye and parallel.
Observe the scale on the refractometer through the viewing window and report the sea water.
