Added a thermometer to a Jobo dev tank: https://juliantanase.com/developing-tank-thermometer/

Cool find.
I wonder what the difference is between the liquid and the plastic material…

For black and white I keep a couple nice thermometers on the shelves where I keep my chemistry. I go off ambient temperature and adjust the time. Mostly it's between 65-70°F. Lower level of my house, former utility room. I'm pretty lucky to have a nice spot.


Even with my famous Jobo processor I have doubts how accurate temperatures are controlled with color. Need a lot of thermal mass for stability.

Very cool thermometer, for sure!

I do usually control and check my temps with a photo thermometer, like everyone else. It's just that I could not help myself not to try this thing, seemed too obvious a choice .
