Analog TDS Total Dissolved Solids Sensor Meter 3.3~5.5V Compatible for Water Quality Testing

Description of the product:

A TDS meter measures the number of total dissolved solids like salts, minerals, and metals in the water. As the number of dissolved solids in the water increases, the conductivity of the water increases, and that allow us to calculate the total dissolved solids in ppm (mg/L).

Although this is a good indicator to monitor the quality of the water, note that it does not measure contaminants in the water. Thus, you can’t rely solely on this indicator to determine if the water is good for consumption or not.

A TDS meter can be useful to monitor water quality in many applications like pools, aquariums, fish tanks, hydroponics, water purifiers, etc.
