What is a salinity meter used for? 20

A salinity meter is a salt content meter. It is an instrument used to rapidly determine the concentration or refractive index of a salt (sodium chloride) solution by weight.

Instruments and equipment for measuring the salinity of seawater. It is often referred to as a conductivity salinity meter.

According to the use, it can be divided into two types: on-site salinity meter and laboratory salinity, and the measurement range is 2 40. On-site salinity meter. It is an instrument that can measure and record the on-site salinity of seawater changing with space and time, and the measurement accuracy is about .

There are two types of measurement circuits: one with automatic temperature compensation and pressure compensation circuit; One does not have a compensation circuit, but inputs the measured values of temperature, depth, and conductivity into a computer and converts them into practical salinity. Laboratory salinitymeter.

High-precision salinity meter with measurement accuracy of approx. Water samples can be measured at constant temperatures, and there are also models with temperature compensation circuits. Both salinity meters typically consist of sensors, measuring circuits, and data processing devices.

There are two kinds of conductivity sensors: electrode type and inductive type: the former has two or more electrodes on the conductivity cell, and the most typical is a four-pole sensor equipped with a pair of current electrodes and a pair of potentiometric electrodes; The latter couples two coaxial toroidal transformers through a single-turn seawater circuit inside and outside the conductivity cell, and the degree of coupling is measured by the principle that the degree of coupling is proportional to the conductivity of seawater.

The details are as follows:

1. The salinity meter has the advantages of quick and easy to use, accurate measurement, light weight and small size, and the instrument can accurately determine the weight of the salt contained in the water, the concentration of the 1000 ratio, and the density of seawater, which is used in the marine aquaculture industry.

2. The method of use is: use a disposable spoon to absorb an appropriate amount of water and drop it on the test plate, look at the white and blue light and dark dividing line inside through the observation port, wipe the objective mirror surface of the refractometer clean, open the condenser version, and attach the seawater droplets to the objective lens, and then light the condenser version.

Here's how to use it:Use a disposable scoop (pipette) to draw an appropriate amount of water onto the test plate.

Cover the test bacteria with a truncated piece.

Look through the observation port to see the dividing line between white and blue light and dark.

of instruments and equipment. It is often referred to as electrical conductivity.

Salinitymeter. According to the use, it can be divided into two types: on-site salinity meter and laboratory salinity, and the measurement range is 2 40.

Salinity meters are used for the rapid determination of salt content (sodium chloride.

Solution weight, percentage, concentration, or refractive index.

It is widely used in salt production, food, beverage and other industrial sectors, as well as in agricultural production and scientific research.

This is because the phenomenon of refraction occurs when light rays enter from one medium to another, and the angle of incidence.

The ratio of the sine is constant and this ratio is called the refractive index. The refractive index of the salt solution can be determined by using the content of soluble substances in the salt solution in proportion to the refractive index in the ordinary environment, so that the salinity meter refractometer calculates the concentration of salt. Note:

The salinity meter is a subdivision type of the refractometer (refractometer).

Thanks to the simple operation, the user can quickly read the salt concentration or the specific gravity of seawater. It can be applied to the concentration management of seawater used in oceans, fisheries, and farms, seawater or artificial seawater used in aquariums, and brine used for fish storage.

Summary. The conversion formula for salinity meter and salt content is: s =

What is the conversion formula between salinity meter and salt content.

The conversion formula for salinity meter and salt content is: s =

The conversion formula for salinity meter and salt content is: s =

Analysis Absolute salinity refers to the ratio of the mass of dissolved matter in seawater to the mass of seawater. Since absolute salinity cannot be measured directly, a corresponding salinity definition has been introduced in practical applications as the methods for determining salinity have changed and improved.

Further Information The main factors affecting seawater salinity are: the relationship between precipitation and evaporation, the precipitation is greater than the evaporation, the salinity is lower; The salinity of the sea area through which the warm current passes is higher, and the salinity of the sea area where the cold current passes through is lower. The salinity of the sea area with a large amount of fresh water injection is low; The more closed the sea area, the higher or lower the salinity.

The conversion formula is: Mass of Salt Mass of Solution Concentration of Salt.

Most salinity meters have two ranges: and ppm. If the brine mass is 10 kg and the salinity meter reads yes, then the salt content is 10 kg kg; If the brine mass is 10 kg and the salinity meter reads 12 ppm, then the salt content is 10 kg 12 10 -6 kg g.

1. Wipe the large objective mirror next to the refractometer clean.

2. Use the dropper to suck a drop of seawater in the seawater tank about 2 3cc.

3. Open the condenser, attach the seawater droplets to the objective lens, and then lightly cover the condenser. Remorse.

4. Aim the condenser of the refractometer towards the light source, and keep the eyepiece close to the eye and keep it parallel.

5. Observe the scale on the refractometer from the viewing window and record the seawater.

6. Because the phenomenon of refraction occurs when light enters another medium from one medium, and the ratio of the sinusoidal of the incident angle is always a constant value, this ratio is called the refractive index. The refractive index of the salt solution can be determined by using the content of soluble substances in the salt solution in proportion to the refractive index of Piqilu in the ordinary environment, so that the salinity meter refractometer can calculate the concentration of salt.

Electronic salinity meter is an instrument used to measure the salinity content in water, which is widely used in water quality monitoring, marine research, aquaculture and other fields. So, how do you measure the dust with an electronic salinity meter?

First of all, you need to prepare the electronic salinity meter and the water sample to be measured. Insert the salinity meter into the water and wait for a while until the reading is stable. In this case, the salinity meter displays a number of salinity levels in the water.

It is important to note that different salinity meters have different reading ranges and accuracy, and they need to be selected and adjusted according to the specific situation.

In addition, when using an electronic salinity meter for measurement, there are a few things to keep in mind:

1.Clean and dry: The salinity meter should be cleaned and dried before use to avoid contamination and damage.

2.Calibration: Calibrate the salinity meter regularly to ensure that the measurement results are accurate and reliable.

3.Maintenance: Clean and maintain the salinity meter in time after use to prolong the service life.

In conclusion, an electronic salinity meter is a convenient, fast, accurate and reliable measurement tool, and it is necessary to pay attention to the relevant operating procedures and maintenance requirements when using it to ensure correct measurement and keep the instrument in good condition.

The details are as follows:

1. The salinity meter has the advantages of quick and convenient use, accurate measurement, light weight and small size, and the instrument can accurately determine the weight of the salt contained in the water, the concentration of 1,000 ratios, and the density of seawater, which is used in the marine aquaculture industry.
