YANTAI STARK INSTRUMENT CO., LTD.

English menu operation:

It has a complete English display and elegant interface: Liquid crystal display module with high resolution is

adopted. All the data, status and operation prompts are displayed in English.

Multi-parameter display: The oxygen concentration value, input current (or output current), temperature values,

time and status can be displayed on the screen at the same time. concentration value in a 10 x 10mm size. As the

main display is eye-catching, the displayed values can be seen from a long distance away. Six sub-displays can

display such information as the input or output current, temperature, status, week, year, day, hour, minute and

second, so as to adapt to different users’ habits and to conform with different reference times set by the users.
