HI 3220-02
Benchtop Meter pH / mV / Temperature with Calibration Check ™

HI 3220 is a pH meter Professional bench, designed to provide results of high accuracy, easy to use both in the laboratory and in the workplace conditions and more difficult.
instrument is equipped with diagnostic features that represent a real improvement in the reliability of measures. The exclusive Calibration Check ™ HANNA allows you to keep under constant review the state of the electrode, so as to always guarantee the optimal functioning. For each calibration, the instrument monitors the condition of the electrode, warning the user when it is necessary to carry out further cleaning.
During the calibration process, the user is guided by clear and simple messages. When calibration is complete, the screen displays a status indicator electrode.
calibration procedure is performed automatically with up to 5 points, with a choice between 7 memorized buffers and 5 custom values. You can also enable alerts “Out of range calibration” and “Calibration expired.”
HI 3220 is equipped with a powerful interactive menu support, which assists the user during all phases of work, the setting of the parameters, the procedure calibration and measurement operations. The context-sensitive help is always available by simply pressing a button.
The tool also allows you to perform ORP measurements with a resolution of 0.1 mV and temperature readings in an extended range from -20 to 120 ° C, using the HI 7662 probe – T.
Data logging can be carried out with three different modes (for pH, mV and ISE):
• automatic recording mode “AutoEnd”: the instrument records the data only when the reading is stable. The user has the ability to set the desired stability criterion, choosing between “fast”, “medium” and “accurate”.
• automatic recording at selectable time interval (from 5 seconds to 180 minutes)
• Recording sample .
For each stored reading, the tool keeps indication parameter, reading, offset, slope, date and time.
instrument can be connected to PC via USB port. For the collection and management of data is available HI 92000 Windows ® compatible software (optional).
