Folks,
Any thoughts appreciated...
I've been doing the jobo main thermostat tweaking that I know is common.
The thermostat is set to 39C which is giving me a dev tank temperature of 38.3.
Tanks were loaded with water at around 35°C and given well over an hour to settle.
Temperatures were measured with the following digital thermometer...

See diagram for the areas measured.
Having read a vast number of pages on the forum it would seem that as I am after a dev temp of 37.8 this would be about bang on once the temp has dropped slightly as it is poured in the tank.
Can anyone confirm this?
I've noticed there's quite a variation across the tank from 39.2 in the bath at the dev tank to 37 in the far right container.
Am I ok to pre-heat the tank at 37 or is the variation too much.
I also cross checked the dev tank with the above thermometer, with Paterson Colour and Jobo Colour thermometers, which range from 38.3 to 40.... which one do I trust?
I am developing 5X4 in Rollei C-41.
Thanks all and Merry Christmas from...
A developer with little experience!
