HI 2211-02 
pH / mV Bench – large display, accuracy and simplicity

The new HANNA HI 2211 is a benchtop instrument microprocessor that measures pH, mV and temperature simultaneously viewing the values ​​on the large display. HI 2211 pH measurements made on a scale from -2.00 to 16.00 pH and can be calibrated at 1 or 2 points, using 5 memorized buffers. During the calibration process, the user is guided by clear and simple messages on the display. The temperature compensation can be automatic (if you use the HI 7662 temperature probe) or manual. HI 2211 also offers the possibility to obtain readings in mV of dual scale (399.9 ± or ± 2000 mV), which can be used to measure the ion concentration, redox potential (ORP) or to check the offset and slope of the pH electrode. Other important features are the function of data storage and the stability indicator reading. HI 2211 is supplied ready for use, complete with glass body pH electrode, temperature probe, electrode holder, adapter and calibration solutions. The tool is compatible with a wide range of pH electrode with BNC connector.
