Product Description

Presto's TDS meter is an all in one solution which is used to measure the TDS i.e. concentration of total dissolved solids of the solution at different modes i.e. pH mode, mV mode, ORP mode, TDS mode, conductivity mode, Salinity mode, Resistivity mode,oC mode, etc. The instrument offers reliable and accurate test results.

The dissolved ionized solid products such as minerals, salts enhance the conductivity of the solution. The TDS meter efficiently measures the conductivity of the solution and measures the TDS of it easily and safely. Apart from this, the dissolved solids like microscope particles and sugar never affect the conductivity of the solution. To measure the TDS of the water accurately, first evaporate the water with the dissolved solutes as residue and then weighing the residue. With Presto’s TDS meter it becomes very easy to test the TDS conductivity of the solutions at different modes.
