Oven Thermometers

I use a laboratory cable thermometer from Omega (model number HH22; see Equipment Sources). It is expensive, but it is far more accurate than most oven thermometers I have tested. It is designed for home use and can be used for two ovens at the same time. It is important for an oven thermometer to be read without having to open the oven because the temperature starts to drop immediately. For an oven with a window, the CDN Model DOT2 has also proven reliable.
