Hanna HI 2211 Basic pH/ ORP Benchtop Mete

Simple to operate
Automatic Temperature Compensation
Automatic calibration
Calibration expiration reminder
ORP range

HI 2211 is a benchtop pH/ ORP and ° C meter. HI 2211 adds measurement for ion concentration ( ISE) and Oxidation Reduction Potential ( ORP) in the mV range.

This instrument also features a reading stability indicator used during calibration and a measurement memory/ memory recall function .

pH measurements for both instruments are compensated for the temperature effect manually or automatically with the HI 7662 temperature probe. This meter is equipped with an easy-to-read LCD which shows both the primary reading and º C.
