A1: What is a salinometer?
Q1: A salinometer is an instrument used to quickly determine the weight percent concentration or refractive index of a solution containing salt (sodium chloride). Digital salinometers are widely used in industrial sectors such as salt, food, and beverage, as well as in agricultural production and scientific research.
A2: How does a salinity meter work?
Q2: Refraction occurs when light enters a medium from one medium to another, and the ratio of the sine of the angle of incidence is constant, which is called the refractive index. The refractive index of a salt solution can be determined by using the fact that the content of soluble substances in the salt solution is proportional to the refractive index in an ordinary environment so that the salinometer can calculate the concentration of salt.
A3: How to use the salinometer?
Q3: The salinometer is immersed in the liquid, and after it is stabilized, the scale is read directly on the salinometer, and the scale shows the salinity of the liquid.
Tips: Can the 3-in-1 digital salinity meter be used in seawater and freshwater?
Yes, the 3-in-1 digital salinity meter can be used in both seawater and freshwater environments. It is designed with a wide measurement range and an advanced conductivity sensor that accurately detects salt levels across different water types.
In seawater, it helps monitor salinity, specific gravity, and temperature to maintain stable conditions for marine life and aquaculture systems. In freshwater, it can detect even small traces of salt, making it useful for hydroponics, water treatment, and environmental testing. This versatility makes the handheld salinity meter an excellent tool for aquariums, fish farms, marine research, and laboratory applications, ensuring reliable performance in a variety of settings.
