KOLO sauna thermometer: a round Fahrenheit dial in black or white
The KOLO sauna thermometer is a round dial that shows how hot your sauna is in degrees Fahrenheit. It reads from 70 to 240 degrees, covering everything from a gentle warm-up to a hot Finnish sauna. The dial is about 5 inches across with a plain Scandinavian face. Pick black or white on the page. KOLO designs it in Finland.
It is a mechanical dial with no battery or wiring, so it works in any sauna, electric or wood burning. A bracket on the back hangs on a single screw, so mounting takes a minute. Hang it on the wall near the bench where you sit, away from the heater, so it reads the air around you rather than the heat rising off the stones. That helps you bring the room to the heat you like every time. Want to track the steam as well? See the KOLO sauna hygrometer, which matches it in size. The KOLO sauna thermometer ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Where should a sauna thermometer be placed?
Sauna temperature is layered, hottest at the ceiling, so mount it where you actually sit: a common placement is on a wall near the upper bench at about head height when seated, away from the heater and not directly above it, so the reading reflects the air on your skin rather than the heat rising off the stones. Your heater manual may specify a spot; follow it if so.
What temperature range does the KOLO thermometer read?
70 to 240 degrees Fahrenheit, which comfortably covers a traditional sauna. Most bathers settle somewhere between roughly 150 and 195 degrees; the top of the scale gives headroom for the ceiling heat of a hot Finnish sauna without pegging the needle. The 4.72 inch (12 cm) round dial is sized to read from the bench, and this listing is the Fahrenheit version of the dial.
How is the thermometer mounted?
It hangs from the bracket on its back on a single wall screw, as the Features tab notes, so mounting is a matter of driving one screw into the paneling at the height you want and hanging the 1 pound dial. There is no battery, no wiring and no calibration, so it works in any sauna, electric or wood-fired, the moment it is hung.
Is a dial sauna thermometer accurate?
A dial thermometer is a mechanical instrument with no batteries or electronics, so it responds steadily rather than instantly. It is accurate enough for what a sauna needs, telling you whether the room is at your preferred heat, though readings will differ a few degrees from one wall to another because the air really is hotter higher up. Mount it where you sit and read it there.
Does it come in white as well as black?
Yes. The Color selector on this page offers the thermometer in Black or White at the same price, matching the two finishes of the KOLO buckets and ladles so your accessories read as one set. The hygrometer in the range is black only, so if you plan to pair the two instruments side by side, black is the finish that matches across both. See the rest of the KOLO range.
Do I need a hygrometer as well?
Not to run a sauna, but it is the natural partner. The thermometer tells you how hot the room is; a hygrometer tells you how much moisture the steam from the stones has added, which is what changes how that heat feels on your skin. The matching round KOLO hygrometer in the same 12 cm size is sold separately, and many people mount the two side by side on the same wall.
