HI5222 is an advanced research-grade dual-channel benchtop pH/ISE/mV meter that can be fully customized via a large color LCD, capacitive touch keys, and a USB port for computer connection. HI5222 features a wealth of functions, including 5-point calibration, selectable resolution, data logging, alarm limits, GLP, and more. It retains simplicity, with both dedicated keys for daily operation and virtual keys that guide the user through setup options.

Four-item measurement

The HI5222 laboratory high-precision water quality analyzer enables fast and accurate measurement of routine important water quality parameters such as acidity pH, redox ORP, ion concentration ISE, and temperature. Both measurement channels support separate pH/ORP electrodes, ISE ion electrodes, as well as separate temperature and reference electrode inputs, enabling simultaneous dual-channel measurement of four parameters. Measurement data from the two channels can be displayed simultaneously on split screens. A new development trend in water quality instruments.

User-friendly operation interface

Supports multiple language selections, with on-screen measurement and calibration operation prompts for convenience and speed.

Powerful user-defined functions

Users can customize the display interface as needed. Basic mode, GLP management mode, and real-time graph display can be set. Up to 10 custom profiles can be stored or recalled, i.e., user-defined settings including: mode, standard points, isopotential point, ISE measurement unit and ISE electrode model, temperature unit, resolution, and other information. When users change measurement items, using the preset custom profile function can greatly save measurement time.

Cal Check TM verification and diagnostic function

HANNA's unique Cal Check TM calibration diagnostic system avoids measurement data errors caused by electrode failure or contamination of calibration solutions during calibration. After calibration is completed, the screen displays an electrode status icon.

ISE ion concentration incremental method

• Ion concentration ISE mode, unique ion concentration incremental measurement method, multiple ion concentration units selectable according to user needs, up to five-point automatic recognition calibration and five user-defined calibrations, with five built-in standard calibration points; storage and recall of up to 200 measurement reports, optional HI92000 software and corresponding data cable for data printing and transfer to PC.

• The ion incremental technique reduces reading errors caused by factors such as temperature, viscosity, pH, or ionic strength; special sample ion concentration detection can be achieved through known concentration addition/subtraction methods.
