Specification of pH/ORP/Temperature Meter Hanna HI 5221-02
HI-5221 is a customisable advanced research grade benchtop pH/mV meter. This meter features a large colour LCD, capacitive touch keys and USB port for computer connectivity.
pH calibration is available for up to five points and the CAL Check features ensures accurate pH readings every time by alerting the user to potential problems during calibration including if the buffer is contaminated or the probe needs to be cleaned.
The calibration data including date, time, buffers used, offset and slope can be accessed at any time along with the current measurement by selecting the Good Laboratory Practice (GLP) display option.
Three selectable logging modes are available: automatic, manual, AutoHold. Up to 100,000 data points can be recorded in 100 lots and can be transferred to a PC via USB and HI-92000 software (optional).

Key features
Precision analysis
- Five point pH calibration
- Input channel: pH/ORP
pH CalCheck
- CalCheck for pH alerts users of calibration status and eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated buffer solutions
- After calibration, electrode condition is evaluated and overall status of pH electrode is indicated
- To avoid taking readings with old calibrations, the instrument automatically reminds the user when calibration has expired
User friendly
- Large log memory with different logging methods
- Multi-language support and contextual help through dedicated HELP key
- Clear tutorial messaging on-screen - available from any mode
- Capacitive touch keypad
- New and improved backlit display
