[Function description]]

1. Probe: Test salt concentration.
2.7 red LEDs respectively indicate salt concentration: 0.3%~ 0.6%(moderate);0.8%~ 1.0%(concentrated);1.3%~ 1.5%(too concentrated).
3.1 Green LED for power indication.
4.ON button: press the button and don't put it down, turn ON the power to test. Release and stop the test.

[Instructions]]

1. Check whether the probe of salt tester is clean. If it is not clean, please clean it with neutral detergent.

2. Put the measured object into a container with a certain height.

3. Press the ON switch of salt tester to see that the Power indicator light is green. If it is not bright, it means that the battery voltage is too low and a new battery needs to be replaced.

4. Extend the probe of salt tester into the solution at least 2cm and test it at least 1cm away from the container wall. The last reading of the bright red light after the display is stable is the detection value.

5. After the test, clean the probe part of salt tester with neutral detergent.

[Eating too much salt in daily life will lead to hypertension]]

Research shows that people who eat 10 grams of salt every day in daily life have a greatly increased risk of hypertension. We should take less than 10 grams of salt every day. Salt meter uses conductivity test to measure salt concentration of liquid food. It can effectively control the daily salt intake and better maintain health. The salt meter contains a touch button, seven red indicator lights to indicate salt concentration, and green power indicator lights, which are easy to operate and easy to use. It will be your good health care.

Salt is indispensable in people's life. The total amount of sodium ions contained in adults is about 60g, 80% of which exist in extracellular fluid, that is, in plasma and intercellular fluid. Chloride ions also mainly exist in extracellular fluid.

High salt harm:

1. Increase hypertension: Many studies have confirmed that, high salt diet it has the effect of increasing hypertension.

2. Promote atherosclerosis: eating more salt can not only increase hypertension, but also increase plasma cholesterol, which can promote atherosclerosis.

3. Gastric cancer: high concentration salt can destroy gastric mucosa and induce gastric cancer.

4. Easy to catch cold: people who eat more salt are prone to catch cold. Because high concentration of salt can inhibit the activity of respiratory tract cells and inhibit their disease resistance; At the same time, saliva can be reduced to make the oral cavity lysozyme reduce and increase the chance of viruses and germs in upper respiratory tract infection.

5. Accelerate the loss of bone calcium: eating more salt is prone to osteoporosis. Animal experiments show that the bone mineral density of rabbits decreases by 50% after 12 months of feeding high-salt feed. Salt restriction and health promotion Chinese Nutrition Society recommends that the daily salt intake of adults should be less than 10 grams, and the World Health Organization recommends a lower salt intake of 3 to 5 grams per person per day.
