The best wood stove thermometer should give you accurate readings. You need to be able to read it easily, so that means you want a good design with clear markings and enough space between each line. Also, if the device has an easy-to-read display then this is also important for whether or not it’s “easy to use”! If there are other helpful features like being waterproof or shockproof then these will make using your new product even easier too.
