Etekcity Infrared Pizza Oven Thermometer

An infrared thermometer takes the guesswork out of preheating your pizza stone, steel, or oven. Point, pull the trigger, and you instantly know the exact surface temperature. This is especially critical for Ooni and wood-fired ovens where temperature varies across the cooking floor.

I use this Etekcity model before every bake to confirm my steel has reached the target temperature. It's also useful for checking dough temperature during fermentation—if your kitchen runs warm or cool, knowing the actual dough temp helps explain why your rise times differ from the calculator's estimates. Incredibly useful tool for under $20.
