After trying other thermometers for my film developing and being disappointed, I decided to give this Patterson thermometer a try even though it seemed a little expensive. Bottom line? I am glad I bought it. It registers the temperature quickly and accurately. It comes in a hard plastic protector case, also, which is good for storage. It was delivered quickly and I am happy with the quality. This is the one that works and that you will use for years.

I really wanted to like this. I've been looking for a really accurate thermometer to check my dial types. First, it arrived with the liquid separated. I wasn't sure what to do. I emailed Paterson but they never answered me. Online I found some ideas, the only one that worked was putting the bulb in slightly boiling water. It was nerve racking and tedious. It did work. It does seem to be pretty accurate, However it's a little hard to read and I'm afraid to break it. So, I used it once, I hope and I'll hold onto it. It's not my favorite piece of darkroom equipment. I do love my Patterson tanks though, only tanks I use even to have others.
