WD-35611-00

The CON 510 benchtop meter is an affordable way to take consistent, accurate conductivity or TDS measurements in your laboratory. The dual display shows both conductivity or TDS, and temperature in °C or °F, plus mode and meter status indicators.

Single- and multi-point automatic or manual calibration. Automatic: up to 4 points (84µS, 1413µS, 12.88µS, 111.8µS). Manual: single or multi-point up to 5 points (one user-selectable point per range for multi-point calibration).


  • Auto ranging across five ranges: offers the best resolution for your measurements.
  • Advanced set up mode: recalls previous calibration data, conductivity/TDS effective cell constants per range, and more.
  • Built-in non-volatile memory: stores up to 50 conductivity or TDS readings with corresponding temperature.
  • Automatic or manual temperature compensation.
  • Selectable cell constant 0.1, 1.0, or 10.
  • Adjustable conductivity to TDS conversion factor and temperature coefficient: gives highest accuracy in any solution.
  • Selectable normalization temperature: choose between 15°C and 20°C.
  • Built-in electrode holder arm; selectable "Ready" indicator; Hold function; diagnostic error messages.
Conductivity Accuracy and Resolution: ±1% full scale or ±1 digit (resolution 0.01 µS, 0.1 µS, 1 µS, 0.01 mS, 0.1 mS)
TDS Resolution: ±1% full scale or ±1 digit (resolution 0.01 ppm, 0.1 ppm, 1 ppm, 0.01 ppt, 0.1 ppt)
