Know before you buy
The thermometer features a magnetic backing that attaches directly to your sauna stove's flue pipe. No tools or drilling are required, making it easy to reposition as needed.
The thermometer is designed for standard metal flue pipes. Because it relies on a magnetic connection, ensure your flue pipe is made of a ferrous metal that magnets can adhere to.
Monitoring the flue temperature helps you maintain an efficient burn. It indicates when the stove is at the ideal temperature for 'löyly' and alerts you when it is time to add more logs, preventing both heat loss and excessive fuel consumption.
No, this is a purely analog device. It operates mechanically, so you never have to worry about batteries or wireless connectivity.
The Min/Max memory allows you to track the temperature range reached during your sauna session. This helps you understand your stove's performance and identify the optimal temperature range for your specific sauna setup.
