I just started using a 9 dollar delta thermometer for processing black and white. I was looking into getting a faster digital thermometer. I understand fully about the accuracy of thermometers (vary from one to the next) and how I would probably be ok just using the delta for black and white. I would like to know a little about the different types of thermometers. I really don?t know much about thermometers in general. Can I use a meat/kitchen thermometer to measure my developer? Does my delta measure the climate temperature as well? Things like that. I don?t know much about thermometers and currently am wondering if they are all the same and used for air/liquid/meat/anything as long as they have the correct range. I know this might sound bad to some of you, but I truly never learned anything about thermometers. Also, does anyone have a recommendation for a nice and fast thermometer for a cheap price? My delta is a little slow for me.
