The Hanna HI-6321 is a high-performance conductivity meter with a sleek, modern design. It has an intuitive interface, Wi-Fi, Ethernet, USB, direct connection options, plus built-in on-screen tutorials.
An included HI-7631233 four-ring probe measures conductivity (μS/cm, mS/cm), resistivity (Ω・cm, kΩ・cm, MΩ・cm), TDS (ppm, ppt), and salinity (ppt, PSU, %). The integrated temperature sensor helps the probe adjust conductivity readings to reference temperatures.
The HI-6321 measures conductivity, TDS, salinity, and resistivity in multiple units:
- TDS is calculated based on conductivity using a customisable conversion factor.
- Salinity (PSU) follows the Practical Salinity Scale, ensuring accuracy in seawater analysis.
- Salinity (PPT) is based on the Natural Seawater Scale, extending from 0.00 to 80.00 g/L for broader applications.
- Salinity (%) represents total dissolved solids as a percentage, offering a different perspective on water composition.
Five measurement display options are available for analytical preferences:
- Basic View - Displays the essential measurement unit and value.
- Simple GLP View - Includes calibration details like offset values and electrode condition.
- Full GLP View - Provides a complete overview with electrode symbols and calibration history.
- Graph View - Live, plotted graphs for real-time trend analysis.
- Tabulated View - Organised tables with timestamps, values, and notes for easy reference.
