Advanced pH/ORP/Temperature Benchtop Meter - HI6221

$1,865.33


Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

The HI6221 is a sleek benchtop meter featuring a large touchscreen display, combining compact housing with an integrated pH/ORP measurement module. Designed for ease of use, the meter comes with Hanna Instruments’ HI1131B double junction combination pH electrode and the HI7662-TW temperature probe.

The HI1131B electrode is constructed with a glass body and features a double junction, refillable design, and a high-temperature (HT) glass indicating sensor. This configuration allows the electrode to perform reliably across various applications, including those involving metals and high temperatures. It connects to the meter via a galvanically isolated BNC connection for secure attachment.

The HI7662-TW temperature probe, made of stainless steel, enables automatic temperature compensation (ATC) for pH measurements. This system addresses complex measurement and monitoring needs, ensuring accuracy, reproducibility, and reliability.

Description

Electrode Holder with Flexible Arm Design

The 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.

 

User Interface

  • 7-inch capacitive touch screen with multi-touch support
  • Capacitive touch back, home and system menu keys
  • User-friendly icons and symbols allow users to easily navigate and interpret the instrument functions
  • 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
    • Tabulated data with date, time, and note

Measurement

  • Measure pH/mV (pH) or mV/Rel.mV (ORP) with temperature
  • Application-specific profiles allow quick and direct measurement without the need to update the sensor and system settings
  • Active log during measurement
  • Measurement stability indicator (using the Stability Criteria setting)
  • Reading modes: direct and direct/autohold
  • Temperature compensation can be Automatic (using temperature probe) or set manually
  • Audible and/or alarm messages for measurements outside of predefined limits
  • Galvanic isolation for pH/ORP measurement

Calibration

The HI6221 features 5-point pH calibration capacity with automatic recognition for standard buffers (Hanna and NIST buffers). In addition, a choice of standard or custom buffers for calibration along with non-volatile memory, which saves data and settings


Logging

Three data-logging types—manual, automatic, & autohold—allows for collection of up to 1,000,000 data points (with time and date stamp for easy reference), and sample ID that’s ideal for manual and autohold data collection.



Connectivity Features & Services

The meter transfers logged data to a USB thumb drive, with log files that include measurements and calibration data in a .csv file. Logged data can be exported via ethernet and Wi-Fi connection and transferred from email and FTP. USB connection includes USB type A for USB stick, keyboard, and printer; and USB type C for USB stick and PC connection. Additionally, a help section for meter guidance features video support presentation of main functionalities.
