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 ºC.
