Two thermometers, two different readings

post #1 of 6
Thread Starter 

I have bought two oven thermometers from two different shops just to make sure my (crazy) oven is on the right temperature. Both gave two different readinds (20 degrees off). How can I tell which one has the correct reading?

Place the thermometers in boiling water. Which ever thermometer is closest to a 100°c is the right one.

They could both be right depending how you placed them. If they weren't right next to each other, it would be pretty easy to have a 20 degree variation in a conventional oven. 

 

If you're going to do the water trick, put the thermometers in a zip locking bag to keep the water out of them.
