Total Dissolved Solids TDS

Send Inquiry
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 Product Features :: Multi range with selectable or auto-ranging options - One tester measures from pure water to waste water! :: Large Display Screen - Displays mode, ATC, battery level and temperature. :: User-Replaceable Sensor - Replace the sensors yourself. Sensors lasts longer with element made of SS316 stainless steel and sensor casing made of VALOX :: Adjustable TDS Factor - Select the appropriate TDS factor from 0.4 to 1.0 for more accurate measurements. :: Waterproof, Anti-roll Design - IP67 waterproof housing keeps tester good even under wet conditions. Unique anti-roll ribbed design ensures firm grip. :: Innovative Cup-style - Innovative sensor housing design can be used as dip-style or cup-style for holding small volume of samples. Sensor casing is made of VALOX for superior chemical durability.
