Sauna thermometer with hygrometer AP-003BW — analog sauna temperature and humidity meter

Analog sauna thermometer with hygrometer AP-003BW by Sauna is a combined instrument designed to measure air temperature and relative humidity inside sauna rooms. The single-dial display shows temperature and humidity values at a glance, enabling straightforward monitoring of sauna climate. The device is suitable for installation in traditional wood-fired and electric saunas and is built for passive, battery-free operation typical of analog mechanical sensors.

Advantages

The AP-003BW provides simultaneous temperature and humidity readings on one clear dial, reducing the need for multiple instruments. Its analog design ensures continuous operation without batteries or power connections, and the scale layout is optimized for typical sauna ranges so users can quickly assess conditions. The compact round housing is suitable for wall mounting in sauna cabins and resists basic sauna environmental factors when installed according to manufacturer guidance.

Suitable for

• Monitoring air temperature and relative humidity in home saunas
• Use in commercial sauna facilities and spa cabins
• Traditional wood-fired and electric sauna environments
• Basic climate control and safety checks before and during sauna sessions

Key specifications

• Display type: analog dial with dual indicators for temperature and humidity
• Measured parameters: air temperature and relative humidity
• Mounting: wall-mountable round housing suitable for sauna walls
• Operation: mechanical/analog, no batteries required
• Design: single combined instrument for space-saving installation

How to use

Mount the thermometer-hygrometer at an appropriate height on a sauna wall, away from direct contact with steam or heating elements, so it measures air conditions representative of the cabin atmosphere. Read the temperature and relative humidity directly from the dial before and during sauna sessions. Use the values to adjust stove settings, ventilation, or water splashes to maintain comfortable and safe sauna conditions. Periodically check the instrument for correct placement and clear visibility of the dial.

Usage recommendations

Install the unit on an interior sauna wall at eye level, away from direct steam flow and the stove, to ensure accurate readings. Avoid placing the device in direct contact with water or on surfaces that exceed recommended mounting temperatures. For reliable long-term performance, inspect the dial for dust or residue and clean gently with a soft, dry cloth when the sauna is cool.
