HANNA HI2211 Basic pH ORP Benchtop Meter

The Hanna Instruments HI 2211 Basic pH/ORP Benchtop Meter is a benchtop pH/ORP and °C meter. The Hanna Instruments HI 2211-01 adds measurement for ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the mV range. The Hanna Instruments HI 2211-01 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 °C.
