I don't know what that is. Is it the nice water temp unit in the first picture?

I have been looking for a temp unit. Can you say anything about this unit. Like does it take batteries, or how is it powered. Was it easy to install or did you need a plumber? How much was it? New or used.

Nice darkroom. Love that 'science-lab' faucet.
