The Harvia Basic SAC92510 is the premier choice for sauna enthusiasts who appreciate functional clarity and reliable performance. Featuring a generous 130 mm diameter round face, this high-visibility instrument is the upsized version of Harvia's popular classic gauge. It is specifically designed with bold, oversized numbers and high-contrast dual scales, allowing you to monitor both temperature and humidity levels effortlessly—even in dim ambient lighting or thick steam.

Nordic Elegance Meets Heavy-Duty Durability

This dual gauge beautifully combines practical utility with Harvia’s legendary manufacturing quality. A striking, polished steel bezel framing the dial gives the meter a clean, modern structure that seamlessly matches contemporary home spas as well as traditional, rustic log cabins. Built to last, the heavy-duty metal housing and premium glass front ensure the internal analog mechanisms remain fully protected against extreme heat and moisture year after year.

Your Complete Climate Overview at a Single Glance

As a combined thermo-hygrometer, this unit lets you check both the temperature and the moisture percentage ($0\text{--}100\text{\%}$) simultaneously with a single glance. Having access to accurate real-time data helps you adjust the steam (löyly) exactly to your personal comfort level, guaranteeing a perfectly optimized wellness session every single time.

Installation Tips for Maximum Accuracy:

To ensure your thermo-hygrometer provides true, reliable readings of your sauna's climate:

• Strategic Placement: Mount the gauge on a wall as far away as possible from the direct, rising radiant heat of the sauna heater to prevent artificial temperature spikes.
• Optimal Height: Install the gauge on the upper section of the wall, positioned at eye-level so it can be easily read while relaxing on the top bench.
