Salinity Meter Use Instruction

Salino meter use instruction

  1. Press the power key to start the device's RDY icon will flash.
  2. Place the gravimeter measurement probe tip (as Shown) in the testing water MEAS icon will flash and the test begins.
  3. The buzzer will sound and the backlight will illuminate to display the result.
  4. Press the power key to display the SG value (unit: PPT), press the key to display the temperature value(unit: C), and press the key more to power off.
  5. Clean the probe ready for its next usage, place the probe in natural water, and wait till the RDY icon appears on the display.
  6. Use fresh water to clean the probe and use a soft cloth to dry it. Keep dry When stored.

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: What are the types of salinometers?
The use can be divided into field salinometer and laboratory salinometer

  • A field salinometer can measure and record the field salinity of seawater at any time spatial changes in the measurement degree range of 0 ± 0.02. There are two types of measurement circuits: divided into automatic temperature, pressure compensation circuit, and no compensation circuit. The uncompensated circuit is to input the measured values of temperature, depth, and conductivity into the computer for conversion to salinity.
  • Laboratory salinometers are high-precision salinometers with a measurement range of 0±0.005. They can measure water samples at constant temperatures. They usually consist of a sensor, a measurement circuit, and a data processing unit.

Helpful in my experiment
I think this salinometer is very good. It helped me a lot with my experiment. My students also use salinometer a lot in the lab.
