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.
