ProfiLine Cond 3110 Conductivity Meter Set 1 WTW. Conductivity is the fastest way to ask how much is dissolved in a water without asking what.
The models differ by 3110 2CA101 and 3310 2CA301.
Conductivity, TDS, resistivity and salinity are the same measurement reported for four audiences. TDS is conductivity multiplied by a factor that depends on what is dissolved, so two meters set to different factors disagree on the same water — always record which factor was used. Resistivity is the reciprocal and is how ultrapure water is specified. Salinity is a conversion written for seawater.
Every conductivity cell has a constant that relates what it measures to what it reports, and that constant changes as the cell fouls, corrodes or gets scratched. Calibrating with a standard close to the value you will measure is the whole of good practice here: a cell calibrated at 1413 µS/cm and used on ultrapure water is calibrated for a different world.
Conductivity rises about 2% per degree, so a reading without temperature compensation is a reading of the room as much as of the water.
Supplied in 2 models.
