The HI3221 is a professional multiparameter benchtop meter. Offering a single input channel, this meter is able to measure pH, ORP, ISE, and temperature. The meter comes with Hanna’s HI1131B glass pH electrode and a temperature probe to allow for automatic temperature compensation. The HI3221 offers many features including CAL Check^™, two-point ISE calibration, data logging, comprehensive GLP data, and PC connectivity via USB to provide users with a simple way to organize and manage their data.
