Conductivity Analysis Module for the HI6000 Modular Series
The HI6000-3 is an innovative hardware module designed for the HI6000 multiparameter modular benchtop instrument. This module allows for easy and fast analysis of conductivity, resistivity, TDS, and salinity, making it ideal for laboratory technicians, industry professionals, and academics. Thanks to its intuitive design, the module installs easily into the dedicated slot behind the instrument, requiring no further configuration. Once inserted, the HI6000-3 is automatically recognized by the system, enabling immediate analysis.

Module Installation
Installing the modules for the HI6000-3 system is simple and safe. Just disconnect the device from the power supply, remove the mounting screws, and insert the desired module into the housing. Once the locking mechanism clicks into place, the module is securely installed and ready for analysis. To protect any unused housings, it is recommended to use the empty covers provided.
Measurement
Choose the unit of measurement:
- Conductivity – μS/cm, mS/cm
- Resistivity – Ω·cm, kΩ·cm, MΩ·cm
- TDS – ppm, ppt
- Salinity – ppt, PSU, %
Calibration
- Conductivity calibration up to 5 points, using:Offset: 0 μS/cm (in air)
Slope: 84 μS/cm, 1413 μS/cm, 5000 μS/cm, 12880 μS/cm, 80000 μS/cm, and 111800 μS/cm, or custom buffers - Salinity (%) calibration using a 100% salinity standard.
USP <645>
The HI6000-3 module also supports the measurement of ultrapure water conductivity used in the pharmaceutical industry. The application includes instrument verification, cell validation, and a guided procedure for the three phases of pure water analysis according to USP <645>. The instrument guides the operator through each phase and notifies when a measurement is out of specification. Detailed reports can be generated and saved.
Recommended Probe
Hanna recommends using the four-ring platinum probe HI7631233 with this module.
The HI7631233 probe is recommended for a wide range of applications in industrial process water treatment. It ensures stable measurements over a broad measurement range and does not require frequent calibrations. An integrated temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation algorithms.
