Conductivity meters

This section of the catalog provides conductivity, resistivity and TDS (total dissolved solids) meters for a variety of media and applications. If you need to measure conductivity in the field, the Pocket Pro Pocket Conductivity Testers and HQ Series Handheld Conductivity Meters are the right choice. All models have a built-in memory for storing and simply reading the measured conductivity values. If your workspace is a laboratory, then we suggest you choose a benchtop conductometer from the HQD series. In addition to conductometers, our catalog contains conductivity sensors in various designs, as well as conductivity standards for accurate calibration of your meter. Hach Conductivity Standards are available in a variety of packaging types and volumes. To select the required conductometer and related products, use the filtering function, the search bar or contact us.
