HI 2211 is a benchtop pH / ORP and ° C meter. Adds measurement for ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the HI 2211 mV range. This tool also has a reading stability indicator used during calibration and measurement memory / memory recall function.
PH measurements of 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 that displays both primary reading and ºC.
