With Maininki, you can monitor both metrics at a glance and adjust your steam session for maximum comfort, relaxation, and effectiveness. Formed over 2.8 billion years ago,Carelian soapstoneis legendary for its durability and thermal properties. It can endure both extreme heat and freezing cold, storing and releasing warmth slowly and evenly. Dense and non-porous, it resists absorbing liquids, flavors, or odors, making it not only functional but also long-lasting and sustainable. By their nature, saunas are not isothermal and may contain varying hot and cold spots. Coil-based thermometers like the Maininki cannot match the precision of digital devices. Each unit is calibrated within a reasonable range and is intended as anindicative tool only, not as a scientific-grade measuring device.
