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, allowing to create dialogue between user and device in a simple and direct language. The interface is entirely in Italian and an online help is always available at the touch of a button.
The help of the color graphic display facilitates the detection of the data, generating real-time graphs and highlighting the most relevant details.
HI 4221 has been designed to make measurements more accurate and complete in pH due to the micron resolution and a wide measuring range (-2 to 20 pH units).
Maximum versatility even in the pH calibration: up to 5 points chosen from among the between 5 and 8 stored values ​​set by the user.
Diagnosis function of the electrodes performs a status check of the electrode during calibration to ensure always use under optimal conditions.
The connection to the PC, either via USB and RS232, and a large data storage capacity complete, finally, what can be described as the best solution for pH measurement in the laboratory.
