Products > By Parameter > Total Dissolved Solids

The total TDS is a mass estimate and is dependent on the mix of chemical species as well as the concentration while conductivity is only dependent on the concentration of chemical species. Some applications require the measurement of Total Dissolved Solids (TDS) in mg/L, parts per million (ppm) or parts per thousand (ppt). The TDS concentration can be obtained by multiplying the conductivity
value with a factor which is empirically determined. Eutech offers meters that allow the direct reading
of TDS values. These include the TDSTestr series, EcoScan TDS 6, CyberScan Standard Portables
CON 11, CON 110 and Waterproof Portable CON 410. Bench meters for advanced level laboratory
research are the CyberScan CON 510, CON 1500 and colour touchscreen research-grade CON
6000.
