5. GENERAL DESCRIPTION & INTENDED USE

HI6221 is a streamlined benchtop meter with a large touch screen display, comprised of a housing

and an integrated pH / ORP measurement module.

Compact and easy to operate, the benchtop meter is delivered with Hanna Instruments HI1131B

double junction combination pH electrode, together with HI7662-TW temperature probe.

HI1131B is a glass body, double junction, refillable pH electrode with an indicating sensor made of

High Temperature (HT) glass. The double junction reference and HT glass design allow the HI1131B

to be used in a wide variety of applications including samples with metals and elevated temperatures.

Probe connection to the unit is secured through a galvanically isolated BNC connection.

HI7662-TW stainless steel temperature probe allows the meter to automatically temperature

compensate (ATC) pH measurements.

This system responds to a complex range of measurement and monitoring requirements, providing

accuracy, reproducibility, and reliability.

HI6221 is supplied with an electrode holder that has a flexible arm. The holder can be mounted

quickly and provides secure support for electrodes while taking measurements in sample containers.

This benchtop meter supports:

• USB type A – support for USB stick, keyboard

• USB type C – support for USB stick, PC connection

The user can select between five different views.

• Basic measurement configuration

• Simple GLP with calibration information

• Full GLP with electrode status and calibration point details

• Live updated, interactive graph

• Tabuled data with date, time, and notes

Capacitive touch screen with multi-touch support

The benchtop unit has a 7-inch color display with 800 x 480p resolution. The capacitive, multi-touch

screen supports video playback and data plotting.

Capacitive keys & icons

Main functions, system settings, and measurement setup parameters are accessed and configured in an

intuitive way, using Menu key ( ), System Menu icon ( ), and Measurement Menu icon ( ).

User interface

User-friendly icons and symbols allow users to easily navigate and interpret the instrument functions.

Using the Menu key ( ) will show Users, System Settings, Log Recall and Help icons.

• The System Menu ( ) permits access to Network, Connectivity, System, and Info tabs.

GENErAL DESCriPTiON & iNTENDED uSE

• The Measurement Setup icon ( ), found in measurement screen, opens sensor setup parameters.

• The Log Recall icon ( ) recalls storred log sessions (Automatic continuous logging, Manual, or

Autohold).
