Conductivity - Hach
1 TDS is an empirically-derived value from the conductivity measurement. Select a value of 0.5 for simplicity and suitability to a wide variety of waters 
Conductivity G uide
Hence in practice, the conductivity meter measures the conductivity at the current temperature (e.g., 27 °C) and converts the measurement value with user.
TOTAL DISSOLVED SOLIDS VS TOTAL DISSOLVED SALTS
One is by determining the conductivity and then applying a 'calculation factor', eg 0.67, which is site dependent. This factor should be determined
