This is wysiwyg! This is just for the display and controller itself. You will need a temp sensor and either a Eb8 or eb4 to use this. I will include a used ph probe but I cannot guarantee that it will work. When I got it from the person it was uncapped. I have been soaking it since I got it so there is a chance it will work after being calibrated. I did temporarily hook it up to my frag system and it did read but was a little high(8.42 when it was 8.20) but I didn't calibrate it before I did that. As you can see in the pics all the ports are in excellent condition.
