Disclaimer: By their nature, saunas are not an isotherm and will have many different hot and cold spots, even within a small area. It is an unrealistic expectation for coil-based thermometers such as these to have an accuracy comparable to a computer-based digital thermometer. Our thermometers are calibrated within a reasonable range. They are indicative only, and are not sold as a scientific-grade measuring device.
