That's exactly the one I have too... expect mine isn't even fancy enough to have a brand on the front. hahaha
I'm wondering if maybe the two prongs are for different things (one for the pH and one for the moisture).
I think the light meter on mine is stuffed... it doesn't do anything unless I put it right up against the light. But the moisture meter is pretty damn good. Don't know about the pH meter though...
