TDS meters are very useful for the following tasks:
1.) Single most important parameter for shrimp (osmotic pressure and mineral content / hardness)
2.) Remineralizing RO water (get your water’s GH/KH levels exactly right by using TDS as a measurement, e.g. 120 TDS for a GH 6 using Salty Shrimp GH+)
3.) Observation of water parameters and overall stability. A sharp rise of TDS is a sign that water parameters are changing rapidly.
4.) Determination of needed water changes (higher TDS = more waste in the water)
5.) Test of Membrane, Filter and DI Resin in RO units. If TDS in pure RO is above 10, a change of filter and/or resin is needed.

TDS meters are used to measure the Total Dissolved Solids within your water column. This can be useful to determine if your RO/DI water has been sufficiently remineralised, and can also be used to determine when a water change is required in your tank, should there be a fluctuation in TDS. Although these meters do not include a calibration screw, these have been tested by the ShrimpCity team to ensure the readings are accurate.
