Question for Richard:

Could a wireless probe be developed at reasonable cost?

I bet it would be popular.

Could a wireless probe be developed at reasonable cost?

No, given the quantities involved it would be prohibitively expensive I'm afraid.

Just wondering about the temperature probe here. I've been reading that different developing agents have different temperature coefficients/reactions to change in temp. Is the option of 4% or 8% compensation truly accurate enough when using many different developer/film combinations?
