lactometer interface to arduino

Hello All, Greetings.
I need to interface a Lactometer (same as Hydrometer) to an Arduino. But looking at it I could not find anything on How to take the data shown by it to Arduino. Its urgent as designing it for the Project. So please help.
Thanks in advance.

It's not urgent.
If it were urgent, you would have thought more carefully about your question, to get the maximum information from answers to it.
