Dual-Gauge Wooden Sauna Thermometer & Hygrometer

Every sauna has a personality — the way heat builds in the corners, how steam disperses from the stones, the subtle shift in air when the door opens. Understanding that personality means understanding two numbers: temperature and relative humidity. This instrument puts both in your line of sight, always.

Twin analogue dials sit side by side — temperature on the left, humidity on the right. The thermometer reads from 0°C to 120°C, covering everything from a gentle warm-up to an intense Finnish löyly. The hygrometer spans 0–100% relative humidity, so you can track exactly how the air changes when water hits the stones.

The solid wood frame isn't decorative — it's functional. Wood naturally insulates the gauges from surface heat transfer, improving accuracy while blending into the warmth of your sauna's interior. It resists the expansion and contraction that warps lesser materials in high-temperature, high-humidity environments.

No batteries. No screens. No firmware updates. Bimetallic coil technology delivers reliable readings through pure physics — the same principle trusted for over a century. A single mounting slot on the rear allows secure wall installation in seconds.

At 25.5 × 13.5 cm, it's compact enough to mount anywhere without dominating the space, yet large enough that both dials remain legible from across the room. It asks nothing of you in return — no charging, no syncing, no maintenance. Just honest, mechanical readings for years to come.
