The Hanna HI 2210 and HI 2211 are microprocessor-based pH and
temperature bench meters.
HI 2211 can also be used for ion concentration (ISE) and Oxidation
Reduction Potential (ORP) in the mV range.
pH measurements are compensated for temperature effect manually or
automatically with the
HI 7662 temperature probe.
The instrument is equipped with a large easy-to-read LCD which shows
the pH (or mV) and temperature simultaneously, together with graphic
symbols.
The calibration process is guided step by step through clear indications on
the LCD. A stability indicator makes the calibration procedure error-free.
