High-precision digital salt meter, capable of measuring a range of 0.0% to 5.0%. - Brand: TANITA - Model: SO-304 - Measurement Range: 0.0% to 5.0% - Temperature Range: 5°C to 90°C - Included: Batteries (2) Thank you for viewing. I purchased this because I couldn't find the salt meter I was using. I used it once. However, I found the one I was using before, so I no longer need this one. There is almost no sign of use, but I used it once, so please refrain from purchasing if you are sensitive to this. Thank you.
