This is the TANITA electronic salt meter, Shiomi-kun (SO-303-WH). I planned to use it for managing my diet after my child was born, but I kept it unused, so I am offering it for sale. The box has been opened, but it has not been used. Since it is unused, I have not checked the operation. Due to storage for several years, the included batteries may also be dead. Please understand the above, and consider purchasing with no claims and no returns. [Product Condition] Unused [Color] White [Measurement Range] 0.4%～1.4% [Measurement Temperature Range] 30℃～90℃ [Power Supply] DC4.5V (3 LR44 type batteries)
