Basic pH/ORP Benchtop Meter
Simple to operate
Automatic Temperature Compensation
Calibration expiration reminder
HI-2211 is a benchtop pH/ORP and °C meter. HI2211 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.
HI 2211-01 (115V) and HI 2211-02 (230V) are supplied with HI 1131B pH electrode, HI 7662 temperature probe, HI 76404N electrode holder, HI 70004 pH 4.01 buffer solution sachet, HI 70007 pH 7.01 buffer solution sachet, HI 7071S electrolyte solution (30 mL), HI 700661 cleaning solution sachet, 12 VDC adapter and instructions.
