Health line / Bowl

Health line
Health line

Health Line continuously recognizes the quantity of salinity while you eat so it helps you adjust the amount of salt and eat. It can be used as a checking instrument that helps you prevent hypertension, heart trouble, and other adult diseases. Or it can be used more friendly and conveniently than a general salinity meter.
It is perfectly waterproof so it is washable. It doesn't use a battery and it is self-powered so it is environment-friendly.
The original color of the band in a bowl is green. Depending on the concentration of salinity, it is changed into yellow and then, red. Once salinity in a bowl is reduced, it goes back to green.
