A non-contact thermometer is useful for measuring the temperature of objects from a distance. This is ideal if you need to find thermal bridges, draughts, air leaks, moisture damage, badly insulated walls, etc. without touching the surface. A thermal imaging camera or IR thermometer is ideal for non-contact measurement of heat from electrical wiring, hot or moving objects where other methods don't work. A thermal imaging camera or IR thermometer can also be used when baking bread or pizza in a wood burning oven or on a pizza stone. It is a handy way to find out if the oven or stone has reached the correct temperature.
