TDS METER 1

WHAT IS TDS?

Total Dissolved Solids(TDS)are the total weight of all solids (minerals, salts, or metals) that are dissolved in a given volume liter(mg/L), or in parts per million(ppm).

The lower TDS level in the water, the more efficiently your body’s cells actually get hydrated by the water you drink.

The higher TDS level in the water, the grater the probability of harmful contaminants that can pose health risks of hinder the on the cellular level

The EPA’S maximum contaminant levels of TDS in secondary drinking water is 500mg/L (500ppm)

Use the TDS METER to

*Check the performance of your water filter

*Check for hardness (1grain=17ppm)

*Make sure you always drink pure water!

Precautions

Do not drop the entire tds meter in the water or dip beyond the maximum immersion level. This unit is not water-tight and is not covered under the warranty is not water enters the unit.

Do not store the tds meter under high temperature or direct sunlight. This will shorten the life-span of the product and potentially void the warranty.

The TDS-1 is calibrated at 50ppm. It is recommended that the calibration level be as close as possible to sample to be tested. If you are testing higher p (member, water quality association)
