I've seen the price of probes : that were capable of .1 and a twenty dollar digital thermometer from Radio Shack : isn't going to do it!! :-) : B&H lists a Jobo analog thermometer with a .1 degree of accuracy for around 55 dollars. An analog thermometer isn't digital/electronic. :-) -- Keep working millions on welfare depend on you ------------------- |

Since Tom answered that .5 is what he uses I assume that .1 is fine.

The second one is a laboratory grade thermometer that I use to check the Besler with every now and again. I send it out for calibration every couple of years. In my case that's not such a big deal as I still have friends that work in calibration labs and they do it for me at no charge. :-) -- Keep working millions on welfare depend on you ------------------- |

Analog vs. digital? I can certainly think of several electronic devices
which are NOT digital. Including some early computers! The thermocouple some electronic thermometers use is an analog device as are whole categories of electronic components. Digital does not always entail more accuracy than analog. A non-digital, non-electronic rectal thermometer is graduated to .1 degree F. and remains accurate over it's life if not abused or broken and can be occasionally calibrated against a certified lab thermometer. On the issue of control strips, it doesn't matter which brand you use as long as you use only one brand and use them in a compulsively consistent manner. On the issue of first developer times for Kodak vs. Fuji films, check for the latest info from Jobo, since it was their info that started this whole controversy, but my understanding is that the first developer time to use depends on the brand of chemicals you use also. I use one brand of chemicals, one time and temp and adjust my EI's from film to film for consistent results. -- darkroommike ---------- "Gregory W Blank" wrote in message news:c1Egd.6040$vJ.2454@trnddc02...
