I bought a new (used) electric kitchen range. 1970’s model for $50 from Craigslist.org.
So I decided to “calibrate” the oven for when I set it to 350 degrees F., the oven heats to that temperature…
Well my cheap oven thermometer said the oven was 300 degrees. And a digital meat thermometer said the oven was 370 degrees!
Note the oven temperature can be adjusted up/down by removing the oven temperature knob and turning a small screw in the hollow shaft or by loosening screws on the back of the knob - moving dial.
BUT!!! It sure helps if I am using an accurate thermometer. Where can I get one?
And for that matter, I need to open the door to read the oven thermometer - can’t read it through the window. An accurate oven thermometer with a “bulb” and line which could be mounted outside of the oven - say sensor mounted inside the oven, then line ran out the back. Gauge mounted on wall in back of oven. That would be great!
Even better would be the above, but one which also reads up to 1000 degrees F. (for self cleaning mode which goes up to around 860 degrees F. on my model).
