All the data are displayed in English. It can be easily operated:

It has a complete elegant interface: Liquid crystal display module with high resolution i

There is no symbol or code that is defined by the manufacturer.

Simple menu structure and text-type man-instrument interaction

It adopts classified menu structure which is similar to that of a computer, clearer and more convenient.

It is not necessary to remember the operation procedures and sequences.

It cane operated according to the prompts on the screen without the guidance of an operation manual.

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.

The main display can show the oxygen 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

users’ habits and to conform with different reference times set by the users.
