● About Salimeter
1What is the recommended daily intake of salt (natrium)?
The World Health Organization’s (WHO) daily sale intake is 5grams. This is relevant to salinity 5% and the recommended intake of natrium is 2000mg. If it’s hard to meet the recommended amount of salt intake from day one, since the salt intake of Koreans are very high, you can change your eating habits by gradually reducing the amount of salt intake by eating more blandly than you usually would eat.
2What is TDS?
TDS is an abbreviation of Total Dissolved Solid. It is a device used for measuring minerals, organic matter, and inorganic matters dissolved in water, which can also be simply used for measuring water quality at home. The level of the value varies according to the amount of electricity flowing between the two sensors. If there is a lot of ionic substance dissolved in the water, whether it’s good or bad, the electricity flow rate will be high, so the level of the value will appear high as well. Just because the TDS values appear high, does not mean the water is bad. What really matters is which and how much of the substance is dissolved in the water. The level of milk and juice value will appear high because they have a lot of ionic substances dissolved in them.
The World Health Organization (WHO) recommended 5grams of natrium intake per day (2000mg)
* United States 8.6g (3440mg) / United Kingdom 9g (3600mg) / Japan 10.7g (4280mg)
Average of daily natrium intake of Korean adults12g(4800mg)
● Product Features
Measures salinity up to 25%
Salinity SR-PRO MASTER model can measure the 0.01% to 25.0% of salinity for not only edible materials but also salty materials, such as pickles and doenjang, soy source and etc.
Amount of natrium / TDS concentration / temperature can be measured
This is a smart salimeter that can measure not only the salinity of the measuring object but also the amount of natrium, TDS concentration, and temperature.
Continuous measurement is possible
If the RDY icon is displayed even after the result value has been displayed, it can be re-measured immediately and the measurement will be complete within a short period of time.
LED Back Light and Alarm Sound
During measurement, the alarm will go on two times. When the measurement is complete, the LED screen light will turn on and the measurement value will appear, along with an alarm sound to indicate completion of measurement.
Water Resistance Function
Due to its water resistance function, it is suitable for places where there is a lot of water use. It can be used anywhere, such as the laboratories, cafeterias, restaurants, and etc.
Additional component of ladle type silicon
The ladle-type silicon is detachable according to the method of use and need. When the ladle-type silicon is attached, the measurement value can more accurate.
* For sanitation, please measure small quantities of food separately by using other tools, such as the ladle-type silicon, rather than to directly touch the food.

● Measurement Method
1After checking the cleanliness of the sensor part, press the power button to turn on the screen, and with the word ON as well as RDY icon will appear to indicate measurement preparation.
2When you immerse the sensor part into the measuring object, the alarm will go on twice and start the measurement. The MEAS icon will flicker on the LED and the results will be calculated. Wait without any movement when it is being calculated. Ladle- type silicon can be used based on your preference.
3The salinity value (%) appears with an alarm and the LED black light turns on to indicate completion of measurement. If you press the button in a consecutive order, the product will display in the order of natrium value (%), TDS concentration (PPM), temperature and OFF.
4After using the product, wash the sensor part with water and neutral detergent, wipe it with a soft cloth and then store it in a safe place. (Wiping it with a rough loofah can be the cause of breakdown.)
*It possible to continuously measure without cleansing the sensor before it goes OFF; however, for accurate measurement, we recommend you to measure after washing the sensor.

*Reference Details for Measuring
- When you immerse the sensor, please measure 1 ~ 2cm away from the floor and the wall, also avoid any contact with the wall or solid ingredients.
- If there is contact with a solid ingredient, the measurement error will vary.
- Measurement of food containing a lot of oil may cause the oil film to appear on the surface of the sensor, which may indicate a lower salinity value than the actual value.
- When the soup is being boiled, the temperature may continuously change, so measurement may be unstable. In that case, turn off the fire or use the ladle-type silicon to measure.
● Battery Replacement
1.Replace the battery when the power does not come on or if the LOW icon flickers on LCD.
2.Use a coin to open the battery cap on the top of the product by turning it in the OPEN direction (in the direction of the arrow).
3.Remove the discharged battery and insert the new battery with the + terminal facing up.
4.Align the bezel on the battery cap with the bezel on the body, press the battery cap lightly, and close it by turning it in the CLOSE direction (in the direction of the arrow).
● Precautions
1. After use, wash the sensor part with water and neutral detergent, and then wipe it with a soft cloth. Do not wipe the sensor part with rough loofah because it is plated.
2. Be careful of burns when measuring hot objects.
3. Since it is water resistant, you can wash it under flowing water; however, do not completely immerse it in water.
4. Use the batteries specified in the standard requirements and do not use chargeable and used batteries mixed together.
5. Be aware of the problems that may occur due to strong impact, which can damage the product and the water resistance function.
6. Store it in a place where it can’t be reached by the children.
7. Avoid storage in a place exposed to high humidity, high temperature or direct sunlight.
8. Do not disassemble or modify this product.
9. When the film is removed, the product can no longer be replacer or returned, so please test the product several times before removing the film.
