Conductivity Bench Meter Advanced

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.

Measurement

• Measure μS/cm, mS/cm (Conductivity); Ω·cm, kΩ·cm, MΩ·cm (Resistivity); ppm, ppt (TDS); ppt, PSU, % (Salinity) with temperature
• Application-specific profiles allow quick and direct measurement without the need to update the sensor and system settings
• Active log during measurement
• Measurement stability indicator (using the Stability Criteria setting)
• Reading modes: direct and direct/autohold
• Temperature compensation can be automatic or set manually
• Audible and/or alarm messages for measurements outside of predefined limits
• Galvanic isolation for conductivity measurement

Calibration

• Standard single point salinity calibration in 100% salinity standard, with the reading salinity scale set to %
• Standard single or multiple conductivity calibration with standards
• Non-volatile memory saves data and settings
