HSE Cedar Sauna Thermometer & Hygrometer - 2-in-1 Mechanical Instrument with Minimalist Design and Glass Dials (Vertical)

• QUALITY CEDAR WOOD - Made entirely with beautiful and aromatic Canadian red cedar wood, the traditional wood of choice in saunas.
• MINIMALIST DESIGN - An elegant, minimalist design to look beautiful in your sauna. Beveled edges, glass casing, and subtly iridescent gold dials display temperature in both Fahrenheit (°F) and Celsius (°C) as well as relative humidity as a percentage (%RH) of the water vapor present in the air compared to the amount needed to achieve saturation at the current temperature.
• NATURAL MECHANISM - Using no batteries, electricity, or dangerous substances, this instrument instead utilizes finely calibrated spirally wound metal strips.
• ANALOG THERMOMETER & HYGROMETER - This natural metal mechanism reacts to changes in temperature and humidity in a way that moves the dials to the correct readings.
• MANUALLY ADJUSTABLE - All HSE instruments are carefully calibrated during assembly, but if your instrument's readings ever become imprecise you can reset the dials back to the correct temperature or humidity level at any time using a flat head screwdriver in the slot found on the back of the unit.

What is a mechanical thermometer? A mechanical or analog thermometer has a metal coil that naturally expands and contracts with temperature changes to change the position of the thermometer's needle. In this way, there are no batteries, electricity, or dangerous substances needed to run the thermometer. The hygrometer works very similarly. Is this as accurate as a digital thermometer? No, please note that this instrument could show a slight difference when compared to digital tools, but provides a great approximation that requires no outside energy sources or dangerous substances, making it a great natural tool for your sauna. moreover, the dial can be adjusted at any time you see fit to continue to give you an accurate approximation well into the future. Please note: For the most accurate readings, hang away from your sauna's heat source (i.e. don't place directly above the heater). Dimensions: 25 x 12.5 x 3 CM
