Using TDS to test water, tap water shows 9 1 and bottled water shows 37. Excuse me: What range of water is healthy drinking water?

TDS pen mainly tests the total dissolved solids in water.

GB 5749-2006 Hygienic Standard for Drinking Water stipulates that the total dissolved solids shall not exceed1000 mg/L/L. ..

The higher the TDS value, the higher the total dissolved solids in water and the lower the TDS value. Tap water shows 9 1 and bottled water shows 37, indicating that the total dissolved solids in bottled water is lower than tap water.
