    อุปกรณ์วัด pH (pH / mV Bench – large display, accuracy and simplicity)

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

    The new HI 2211 HANNA is a tool bench microprocessor that measures pH, mV and temperature simultaneously displaying the values ​​on the large screen. HI 2211 performs pH measurements on a scale from -2.00 to 16.00 pH and can be calibrated to 1 or 2 points, using 5 buffer values ​​stored. During the calibration process, the user is guided by clear and simple messages on the display. Temperature compensation can be automatic (if you use the temperature probe HI 7662) or manual. HI 2211 also offers the possibility to obtain mV readings in 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 data store and the stability indicator reading. HI 2211 is supplied ready for use, complete with pH electrode with glass body, temperature probe, electrode holder, adapter and calibration solutions. The tool is compatible with a wide range of pH electrode with BNC connector.
