HI6321 is a streamlined Conductivity/Resistivity/Total Dissolved Solids (TDS)/Salinity/Temperature benchtop meter with a large touch screen display, comprised of a housing and an integrated conductivity measurement module. Compact and easy to operate, the HI6321 includes Hanna’s HI7631233 four-ring conductivity/resistivity/TDS/salinity probe.
Recommended for a wide range of industrial process water applications, HI7631233 provides stable measurements over a wide measurement range and does not require frequent calibrations. An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation algorithms:
Linear: appropriate when it is assumed that the temperature coefficient of variation has the same value for all measurement temperatures.
Standard: appropriate for high-purity water measurements and documented in ASTM Standard D5391-14. This setting should be used for >1Mohm.cm resistivity measurements.
Natural: appropriate for natural ground, well, or surface water (or water with similar composition) in accordance with ISO7888 standard.
