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

HI 4222-02
Multi-Tool with 2-channel 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, 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 4222 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).
HI 4222 is also provided input for measurements with ion-selective electrodes and the tool provides the main methods for incremental steps. Maximum versatility also in the calibration: up to 5 points chosen from among the 8 stored between 5 and values ​​set by the user.
Diagnosis function of the electrodes performs a status check of the electrode during calibration to ensure more use in optimum conditions.
Connecting 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.
