YANTAI STARK INSTRUMENT CO., LTD.

Complete English display, English menu operation: 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 time  

and status can be displayed on the screen at the same time. The main display can show the oxygen concentration

value, hilite, far visual range. Sub-displays can display such information as the input or output current   

temperature, status, week, year, month, day, hour, minute and second etc, so as to adapt to different users’ habits

and provide reference times of instrument.
