HI-6000-3 EC MODULE FOR HI-6000 SERIES BENCH MULTIPARAMETER

The HI6000-3 module measures conductivity over an extended range from 0.001 µS/cm to 1 S/cm, TDS, resistivity, salinity and temperature.

The HI6000-3 module also supports the measurement of high purity water used in the pharmaceutical industry. The application includes meter verification, cell validation applications and the HI6000-3 module is programmed for the three stages of the USP <645> bulk water analysis. The meter guides you through the measurement steps and notifies you when a measurement is out of specification. Reports can be generated and saved.

Measurement

• Choice of Measurement Unit

• Conductivity – μS/cm, mS/cm

• Resistivity – Ω·cm, kΩ·cm, MΩ·cm

• TDS – ppm, ppt

• Salinity – ppt, PSU, %

Calibration

• Conductivity Calibration up to five 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 standards

• Salinity (%) calibration using 100% salinity standard

Required probe

Hanna recommends the HI7631233 platinum four-ring probe for use with this module.

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. A built-in 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.
