The Horiba DS-71 meter is designed for laboratory testing of conductivity, resistivity and salinity with a single electrode. Because these three variables are all measured using the same method they can be determined with a single test and derived from the resulting conductivity measurement.


The Horiba DS-71 comes with a 3552-10D Conductivity cell which has a measurement range of 0.00 μS/cm to 199.9 mS/cm. This conductivity cell is submersible, designed for general purpose testing and is a great tool for most conductivity testing situations. Other conductivity cells can be used with this meter to fit special testing circumstances. The complete list of conductivity cells can be found here.


Note: The DS-71 does not include a color touch screen, it features the standard LCD screen.
