Benchtop pH/mV Meter with CAL Check™
The HI2221 is an affordable pH/mV benchtop meter that features automatic pH calibration up to five-points that can be performed using seven standard buffers. All pH measurements are compensated for temperature effect automatically with the supplied HI7662 temperature probe. The HI2221 can also measure oxidation reduction potential (ORP) in the mV range using ORP electrodes. The HI2221 offers many features including CAL Check™, data logging up to 100 records, GLP (Good Laboratory Practice) capabilities, and PC connectivity via USB to provide users with a simple way to organize and manage their data.
