Rento Sauna Thermometer

For the most accurate temperature readings, mount the thermometer on a wall between 6 and 12 inches below the ceiling. Avoid placing it directly above the heater or near the door, as these areas can cause inaccurate temperature fluctuations.

No, this is a purely analog instrument. It uses a mechanical bimetallic coil to measure temperature, so you never need to worry about batteries or electrical connections.

This model is specifically designed for indoor sauna environments. While it is built from durable anodized aluminum, it is not calibrated or sealed for outdoor weather conditions.

The thermometer features a high-contrast design with a black brushed aluminum face and clear markings. While it is not illuminated, the large 6-inch square face makes it easy to read at a glance in typical sauna lighting.

Like any metal object inside a sauna, the thermometer will absorb heat. While it is safe to have on the wall, you should avoid touching it directly during or immediately after a sauna session.
