I put cold water into the processor and warm it up with the ready mixed chemicals in the measuring beakers and at the same time float the dev tank in the water until it is at the operating temp. That ensures the developer goes into an already warm tank so the drop in temperature does not occur. So in your case float the dev tank in the waterbath for no less than 10-15 mins and that should be enough to warm the tank. |

Hi John, this is exactly what I do, but there is still a measurable temperature drop in the developer temperature. However you wouldn't have the opportunity to measure it in a Job processor. |

You might want to leave the tank (and all of your chemicals too ?) in the tempering bath for perhaps 20 min to get it to the correct temperature. A kettle full of warm/hot water to help maintain your tempering bath is a great help. A tempering bath also works in hot weather too - preventing all the temperatures from drifting high. Depending on the temperature of your cold tap water, it sometimes pays to prepare a few litres of tap water and put it in the fridge overnight. I never put any developer/stop/fix in the fridge - just tap water. Martin |

You could always do a dry run first with a damaged film in the tank and by using plain water at 40c check the temp after a few mins to see what it is resting at. |

John, Thanks for the dry run idea! That way I’d know for certain whether the temperature was going to be correct before committing. I suspect that this is a case of ignorance being bliss; if I had just assumed that the temperature was correct, then I wouldn’t be worried. At the end of the day I guess it’s mostly a matter of consistency. Sent from my iPhone using Tapatalk |
