HI-6321 Advanced Conductivity Benchtop Meter

The HI-6321 conductivity meter from Hanna Instruments is an ideal solution for laboratories, with a modern, efficient design and practical user interface for repeatable, reliable testing. Multiple efficiency features are included with the HI-6321, including practical data transfer options with WiFi, ethernet, USB stick and direct connection and easily accessible on-screen tutorials.

This research laboratory-grade EC benchtop meter is supplied with the Hanna HI-7631233 four-ring probe for the measurement of conductivity (μS/cm, mS/cm), resistivity (Ω・cm, kΩ・cm, MΩ・cm), TDS (ppm, ppt) and salinity (ppt, PSU, %). This purpose-built advanced probe makes the HI-6321 well-suited to a wide measurement range across various industrial process water applications.

The HI-7631233 includes an integral temperature sensor, allowing the measured conductivity to be adjusted to a reference temperature through the application of specialised compensation algorithms.

HI-6321 Laboratory Conductivity Meter Features

Practical, streamlined design

The HI-6000 series are streamlined meters designed to suit the requirements of modern laboratories. A practical, smaller footprint and simple design with a large, capacitive touchscreen that can be used even with gloves on make this EC meter a practical choice. The electrode arm can be swapped to either side of the meter, providing greater flexibility in placement within the lab.

Supplied with Hanna four-ring probe

The HI-6321 conductivity meter is supplied with the Hanna HI-7631233 probe for the measurement of conductivity, resistivity, TDS and salinity, with an integral temperature sensor. This purpose-built four-ring probe does not require frequent calibration and covers a comprehensive measurement range for all key parameters.

The integrated temperature sensor enables adjustment to measured conductivity through the application of one of three specialised compensation algorithms:

• Linear: appropriate for use in measurement where the temperature coefficient of variation has the same value for all measurement temperatures
• Standard: appropriate for use in high-purity water measurements and>1Mohm.cm resistivity measurements
• Natural: appropriate for use in natural well, ground or surface water or any water with a similar composition (ISO 7888 standard)

Electrode holder included

A dedicated electrode holder is included with the HI-6321 EC lab meter, allowing you to securely hold your probe while measuring samples. The holder can be mounted on either side of the meter, providing flexibility in placement in the laboratory.

Reliable and accurate measurement

The HI-6321 conductivity meter is designed to be exceptionally accurate in measuring TDS, conductivity, salinity and resistivity across a wide range with the ability to measure in multiple units for each parameter:

• TDS: TDS is both a calculated value based on the solution’s conductivity (factor x EC25) and is a conversion factor to measure EC in ppm
• Salinity PSU: The practical salinity of seawater relates the ratio of electrical conductivity of a normal seawater sample at 15 °C and 1 atmosphere to a potassium chloride solution (KCl) with a mass of 32.4356 g/Kg water at the same temperature and pressure. Under these conditions, the ratio is equal to 1 and S=35. The practical salinity scale may be applied to values 0 through 42.00 psu at temperatures between 0 to 35 °C.
• Salinity PPT: measurements expressed in ppt are based on the Natural Seawater Scale that extends from 0.00 to 80.00 g/L and covers the 10 to 31 °C temperature range. It determines the salinity based upon a conductivity ratio of sample to standard seawater at 15 °C and an approximate salinity value of 35 in seawater.
• Salinity %: in this scale 100% salinity is equivalent to roughly 10% solids.

Flexible configuration and design

The ability to connect via WiFi and ethernet with no requirement for a PC or printer connection allows greater flexibility in where the HI-6321 can be placed in the lab. The configurable electrode arm provides further flexibility in placement, allowing the advanced meter for EC to be placed up against a wall on either side as required.

Five measurement view options

Five different measurement views are available for the HI-6321, offering a variety of data options to suit individual requirements:

• Basic View: A simplified view including the measurement unit and measured value
• Simple GLP View: Including displays of the latest calibration date and time, Offset value, average slope and electrode condition.
• Full GLP View: Complete display including the electrode symbol and used buffers tray in addition to the above.
• Graph View: A live, plotted graph of the measured value.
• Tabulated View: Data presented in a table with measured values plus date, time and all notes made during measurement.

Extensive capacity for data

The HI-6000 series meters feature an expanded capacity of data storage, with up to 1 million data points stored at any time, inclusive of both the time and date stamps for easy filtering. Data is exported in a universal .csv file and accessible via ethernet, connection to a PC or printer or WiFi.

Visual and audible alarm system

A robust, customisable alarm system is available within the settings of the HI-6321, with options for audible and visual warnings. Correct ranges can be input directly into the alarm, activating when a measurement exceeds these predefined limits when testing.

Connect via WiFi and ethernet

Share data directly with FTP and email transfer over WiFi and ethernet, allowing .csv data from measurements to be immediately sent to local PCs and remote locations as necessary with no additional steps in external software required.

Transfer with USB A and C

The HI-6321 includes both USB C and A connection, allowing for peripherals such as a keyboard to be used with the system as well as providing connectivity to PCs and laptops. Additionally, data can be transferred via a USB memory stick in .csv format, providing immediate access to test data without needing extra software.

In-built video tutorial system

All HI-6000 series advanced meters include a comprehensive tutorial HELP functionality, providing on-screen instructions for the main functionalities of these laboratory-grade meters. Both video and text instruction are available to suit your preferred learning style.

Complete customisability for users

Create and edit custom users directly on the HI-6321, with both standard and administrator options. Administrators can manage and create accounts directly from the Account Management Screen, with customisable configurations to provide limited or full access for additional users.
