Koreans invent “salt sensor”
The Chosun Ilbo reports that South Korea’s Rural Development Administration has invented a portable “salinity sensor” to test the salt concentration of soups and other liquid foods.
After some additional testing in Korean hospitals, government officials hope to make it available to the general public within a year at an estimated cost of W25,000 (US$1=W1,246) per unit. The tester uses a small electric current to measure the salinity of a liquid.
Is it just me or does this salt tester look like a home pregnancy test?
