Reading Digital TDS Meter Output with Arduino and Displaying on LCD

Question: I have a TDS meter with a digital output that I would like to interface with my Arduino and display the data on an LCD screen. Specifically, the meter I have outputs a digital signal . Is it possible to connect the TDS meter to the Arduino in this way and read the data with my code? What circuitry do I need to connect the two devices, and are there any sample code or tutorials available for this kind of project? Additionally, how do I convert the digital output to a readable TDS value, i have not a tds sensor just tds meter can this is possible ? Any help or guidance would be greatly appreciated. Thanks!

What sort of digital output is it? Do you have a link to the user manual that describes this output and the format of the data generated?

I do not believe this meter is designed to support an external connection. DFrobat sells an Analog TDS Sensor/ Meter for Arduino for about $12US. Modifying the meter you shows will be time consuming and probably expensive. Look here: What is tds meter - DFRobot TDS Meter Sensor With Arduino - DFRobot
