    อุปกรณ์วัด pH (2-channel Multi-Tool with color graphic display, ISE measuring direct and incremental, 230Vac)

    HI 4222-02
    2-channel Multi-Tool with color graphic display, ISE measuring direct and incremental, 230Vac

    HI 4222 is a state of the art in measurement of pH. The new user interface enhanced by the large color graphic display with backlight, enables a dialogue between user and device in a simple and direct language. The interface is entirely in Italian and online help is always available at the touch of a button.
    ‘s use of color graphic display facilitates the identification of the data, generating real-time graphs and highlighting the most important parts.
    HI 4222 is designed to make measurements more accurate and complete pH with a resolution micron and a wide measuring range (-2 to 20 pH units).
    HI 4222 is also provided input for measurements with ion-selective electrodes and tool provides the main methods for incremental measures. Versatility also in the calibration: up to 5 points to choice between 8 and stored between 5 values ​​set by the user.
    diagnosis function performs a check of the electrodes the electrode status during calibration to ensure always use in optimal conditions.
    Connection to a PC, either via USB or RS232, and a large data storage capacity complete, finally, what can be described as the best solution for the measurement of pH in the laboratory.
