I have a beautiful classic glass and stainless Kodak Process Thermometer but although it is great for use as a standard to calibrate to, for obvious reasons I'd rather not use it for daily darkroom duties. I have a Premier dial thermometer that can be calibrated but everything else about it is awful, its scale goes from 15c to 70c so the degree increments are infinitesimal and 20c is way down at the lower extreme of the scale, parallax is a problem and the needle vibrates unreadably with the slightest touch. A new thermometer is the single improvement that would make my darkroom life immeasurably easier. I'd like to find something that is accurate, can be calibrated, easy to use and read, designed for the Black and White processing range and rugged enough for everyday use. Either Dial or digital. Any suggestions?
