Conductivity, resistivity, and TDS (total dissolved solids) meters are available for a variety of environments and applications. When you need to measure conductivity in the field, our pocket conductivity testers and portable conductivity meters may be the right choice for you. Many models have an onboard memory to store and recall conductivity readings taken. If the laboratory is your base, select from benchtop conductivity meters. Conductivity meters can include a USB or RS-232 computer interface.
