Oven thermometers (not cooking thermometers)
I recently moved into a new apartment. The oven is a cheap, gas oven with a dial to set the temperature and no display of any variety. The dial also has had all the writing worn off, so I have been guessing at how hot the oven is based on how quickly water evaporates when I toss a drop onto the oven floor (a surprisingly reliable test, if you've had the practice).
I can buy a cheap oven thermometer at any store (the type that dangles from a rack); however, I've always found those to be completely unusable, since you have to open the door and put your face in front of 425 degrees to get a read on it. I figured there has got to be some kind of digital system that works like the probe style cooking thermometers (i.e. can run a cord outside the oven with a digital display), except it tells you what temperature the oven is at rather than your meat.
I cannot find such a tool, however. Mainly the problem is searching for "oven thermometer" gives me pages and pages of probe and instant read thermometers. Any leads? I just want something that tells me what temperature my oven is without having to open the door. If they don't exist, I guess I could hack something up with a probe thermometer (clip the probe to a rack), but that's a last resort.
