Hannaâs HI 210 and HI 211 are microprocessor-based pH and Temperature bench meters.
These instruments are equipped with a large easy-to-read LCD which shows the pH (or mV) and temperature simultaneously, together with graphic symbols.
HI 211 can also measure ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the mV range.
The calibration process is guided step by step through clear indications on the LCD. A stability indicator makes the calibration procedure error-free.
pH measurements are compensated for temperature effect manually or automatically with the HI 7669/2W temperature probe.
