click to enlarge The Model 4200 Conductivity/ TDS Meter is designed and constructed to resist the harshest of field, laboratory and industrial environments. The whole system is waterproof to IP67, and if dropped into water will float. These products are ideal for on-site water quality measurement in a multitude of customer applications.

The measuring range from 0 to 199.9mS is covered by 5 automatically switched ranges using a single cell. Additionally, the in-built software is able to calculate and report results as TDS ( Total Dissolved Solids) in mg/ l; Salinity in g/ l or Resistivity in Mohms. In the TDS mode the 4200 allows a variable factor to be applied to the measured conductivity value.
