Sous Vide Cooker = Color Tempering Bath Heater?

[Kino]

This might be the thing for very accurate temperature in a DIY tempering bath for color.

According to the ad, it can handle 19 liters or a little over 5 gallons of water and maintain a 0.1 degree temperature from 77°F-211.8°F (25-99.9°C). It would, of course, only be able to heat; you would need a source of chilled water to maintain anything below what is the temperature of your house water supply.

At $100 USD, that would be a cheap way to make a tempering bath for developing tanks, eh?

Edit: you can even buy plastic balls that float on the surface of the bath to retain the heat...

It's nice! I would have bought it back when I still do darkroom work. I did made inexpensive and accurate tempering bath but I found the biggest problem is how to keep the temperature constant once the chemical is poured into the developing tank.

I use a sous-vide for heating my Potassium Oxalate developer for platinum/palladium printing. I run it at 140 F, which is much warmer than required for C-41 or E-6.

Ah... yes indeed,
A nice sous vide,
Is what you need,
My words, you heed!

C-41 2 minutes at medium rare. Ha!
Seriously 3'15" is all you need to worry about. I agree that what the temperature in the tank is what's hard to judge. I have a mixing valve I set it for 100 F and warm the tank with water. Ideally you preheat the tank dry.
Slide processing is a bit more picky.

That is a great idea, but I use a 16 quart Coleman cooler provides very good temperature control. I have never had an issue with E-6.

However, I have been wondering about building a kit to use when camping where temperature control would be a lot trickier. With something like that, you could have a darkroom anywhere there was electricity.

I use an Anova Sous Vide that I purchased specifically for that purpose. Works great!
