Where ancient soapstone meets traditional steel metal, the Hukka Pisarainen Soapstone thermometer is delicately carved in the form of a droplet. The simple design of the droplet steam thermometer is excellent for many types of saunas at home or in a cottage. Gage the perfect time to enter your sauna to achieve the most enjoyable sauna experience. Suitable temperature, proper humidity and good ventilation are the essentials for your sauna experience. 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.
