อุปกรณ์วัด pH (Benchtop pH meter with color graphic display)

HI 4221-02
Benchtop pH meter with color graphic display

HI 4221 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 4221 was designed to make measurements more accurate and complete pH with a resolution micron and a wide measuring range (-2 to 20 pH units).
Maximum versatility also in pH calibration: up to 5 points to choice among between 5 and 8 stored values ​​set by the user.
diagnosis function performs a check of the electrodes the electrode status during calibration to ensure that they always use under optimal conditions.
Connection to a PC, either via USB or RS232, and large capacity data storage complete, finally, what can be described as the best solution for the measurement of pH in the laboratory.
