MODERN, EASY TO USE INTERFACE

There are two basic and advanced interfaces: with or without GLP information, real-time, and data logging.

COLOR LCD GRAPHIC DISPLAY

Graphic display, and customizable color configuration. The display allows real-time and virtual keys to provide intuitive user support.

TOUCH KEYBOARD

Capacitive touch keypad for precise navigation of menus and screens. There are 4 dedicated keys used frequently including calibration and switching measurement modes and 4 virtual keys that change when used. Capacitive touch technology ensures the buttons never get stuck.

USB PORT

Data can be transferred to a computer with the USB cable and HI92000 software.

DATA LOG

– 3 logging modes are available on the HI5221: automatic, manual, and AutoHold.

– Manual and automatic recording of up to 100 batches with up to 50,000 records/batch, for a total of up to 100,000 data points.

– Automatic recording feature to save data by time and sampling interval.

CAL Check™

Hanna Instruments exclusive CAL Check™ feature alerts the user to problems during calibration such as contaminated buffers or probes that need to be cleaned or replaced.

AUTOMATIC CALIBRATION

– Calibration has automatic, semi-automatic, direct buffer recognition and direct manual entry options

– Automatic calibration is available for 2 points at 0% and 100% saturation or 0 mg/L and 8.26 mg/L. One standard User options are available for a user-defined value.
