HI6321 is a streamlined Conductivity/Resistivity/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.
The result is reliable electrolytic conductivity (EC), TDS (Total Dissolved Solids), resistivity, or Seawater Salinity in percent, psu, or ppt units.
