Conductivity TDS

Conductivity TDS standards are calibration solutions for meters that report total dissolved solids rather than raw conductivity. Drinking water, aquaculture, horticulture and environmental laboratories use them to check TDS readings against a known value.

The nine Reagecon products here cover a practical spread of concentrations: 10 mg/L, 100 mg/L and 1000 mg/L total dissolved solids standards, together with a 1382 ppm NaCl standard at 25°C for meters that calibrate on a sodium chloride scale. Each is a ready-to-use solution with its value stated on the label.

When selecting, check whether your instrument expects a TDS value in mg/L or an NaCl-equivalent in ppm, and pick the standard closest to your typical sample range. Meters calibrated at one point generally read most accurately near that point. If you measure conductivity directly, the Conductivity Standards section is the better fit.
