Conductivity/TDS/Resist/Salinity Meter Advanced Serie6

Model HI-6321-02

Condition New

Item no. HI-6321-02

More details

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

Logging

Data log collection of up to 1,000,000 data points (with time and date stamp)
Logging types: manual, automatic, and autohold
Sample ID for manual and autohold data

Connectivity Features & Services

Transfer logged data to a USB thumb drive
Log files that include measurements and calibration data (as .csv file)
FTP and email for log export via Ethernet and Wi-Fi connection
USB type A for USB stick, keyboard, and printer
USB type C for USB stick and PC connection
