Is there nothing on the label you could google?

Temperature sensor connected to a B.M.S system like Trend.
The one in the picture is made by Titan

AH!.........took a minute to work that out!
I was talking about the corrosion on the elbow (that's what it looks like on that photo to me anyway) .
It made me think of the reactivity series, de-zincification and how we never used to use brass fittings on hot water systems as a rule. I was asking a question of @YorkshireDave as he was on here at the time but that was yesterday and alas, the question has slipped my mind. It will hopefully return soon. If it does, I will be back with it.
