Advanced pH/ORP Benchtop Meter – HI6221-02

Advanced pH/ORP Benchtop Meter – HI6221-02

Measure pH/mV (pH) or mV/Rel. mV (ORP) with Temperature

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.

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 notes

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 o 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

• 5-point pH calibration with automatic recognition for standard buffers (Hanna and NIST buffers)
• Choice of standard or custom buffers for calibration
• Non-volatile memory saves data and settings

Logging

• Data log collection of at least 1,000,000 data points (with time and date stamp)
• Logging types: manual, automatic, autohold
• Sample ID for manual and Autohold data

Connectivity

• Transfer logged data to a USB thumb drive
• Log files that include measurements and calibration data (as .csv file)
• FTP and email for log export via Ethernet and Wi-Fi connection
• USB type A for USB stick, keyboard, and printer
• USB type C for USB stick and PC connection

Help section for meter guidance
