Sorry, but the web-site doesn't have the recipe; they have a book that contains the recipe ! I'm not sure what the legal implications are if I put it out on this forum.
I measure temperature using a digital thermometer, which I've compared to my Jobo "high resolution" mercury thermometer. Both point to the my CPE being about right on the temperature setting. However, I think the best plan is to measure the temperature of the developer directly, rather than rely on a thermostat.
I rather glad that digital has caused the price of these processors to crash. I would hate to have paid full price for one. Has your sprung a leak yet. Mines held together with silicon sealant !
Thanks for the welcome
