unico7202B portable visible spectrophotometerIn addition to having the same optical path structure and online function as the 7200 model, it uses a 4-row LCD display, the instrument automatically sets the wavelength, adopts a menu style operation interface, can store experimental data, and can establish and store 25 first-order linear standard curves. It also has clock display and setting functions, and a friendly human-machine dialogue interface. For the convenience of field work, battery boxes, chargers, and portable instrument cases can be optionally selected.
