HANNA Instruments HI-5221 [HI5221-02] Research Grade pH / ORP / Temperature Benchtop Meter

The HI5221-02 is an advanced research grade benchtop pH/mV meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5221-02 is rich in features including five-point calibration, selectable resolution, data logging, alarm limits, comprehensive GLP, and much more. This meter retains simplicity with both dedicated keys for routine operation and virtual keys that guide the user through setup options.

The HI5221-02 ensures confidence in measurements with the exclusive Hanna Instruments CAL Check™ feature that alerts the user to potential problems during calibration including if the buffer is contaminated or the probe needs to be cleaned.

The HI5221-02 features a universal BNC connection for use with the expansive line of pH and ORP electrodes that Hanna Instruments offers. The meter is supplied with the HI1131B glass body, double junction, combination pH electrode that operates over a wide temperature range from 0 to 100°C.  All readings are automatically compensated for temperature variations with the separate HI7662-T temperature probe that is included.

The HI5221-02 can be calibrated up to five points with a choice of eight preprogrammed buffers or five custom buffers. The HI5221-02 features Hanna’s exclusive CAL Check™ to alert the user of potential problems during the pH calibration process such as “Electrode Dirty/Broken” and “Buffer Contaminated.” The overall probe condition based on the offset and slope characteristic of the electrode is displayed as a percentage after calibration is complete. 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 and AutoHold logging. Up to 100,000 data points can be recorded in 100 lots with 50,000 records max/lot and exported to a computer for data review and storage.
