Research Grade pH/ORP Meter with CAL Check, 230V

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).

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.
