Sauna Thermometer with Hygrometer AP-030BW — analog sauna temperature and humidity gauge

The Sauna Thermometer with Hygrometer AP-030BW is an analog instrument designed to measure both air temperature and relative humidity inside sauna and steam-room environments. The combined dial displays temperature in degrees and relative humidity percentage, allowing users to monitor the sauna climate continuously. Built for indoor sauna mounting, this compact gauge helps maintain recommended temperature and humidity ranges for comfortable and safe sessions in private and commercial saunas, spa facilities, and wellness areas.

Advantages

This analog sauna thermometer with hygrometer provides simultaneous readout of temperature and humidity on a single dial, simplifying climate assessment. Its mechanical design requires no batteries and offers immediate visual feedback suitable for quick checks during sauna operation. The durable housing and clear markings are intended for the high-temperature, high-humidity conditions typical of sauna rooms, enabling reliable monitoring with minimal maintenance.

Suitable for

• Private home saunas and steam rooms
• Commercial sauna facilities, spas, and wellness centers
• Monitoring sauna climate during heating and pouring water on stones
• Routine checks to maintain safe temperature and humidity levels

Key specifications

• Measurement type: analog temperature and relative humidity on a combined dial
• Temperature scale: degrees Celsius
• Humidity indication: relative humidity percentage
• Mounting: wall-mounted for indoor sauna use
• Power: mechanical operation — no batteries required
• Construction: heat- and moisture-resistant casing suitable for sauna environments

How to use

Mount the thermometer with hygrometer at eye level on an interior sauna wall away from direct steam jets and the heater to obtain representative air measurements. Allow the instrument a few minutes to equilibrate after the sauna reaches operating temperature. Read the temperature in degrees on the dial and the relative humidity as a percentage; use these values to judge comfort and steam intensity. Periodically inspect the gauge for condensation or damage and clean the exterior with a damp cloth when the sauna is cool.

Usage recommendations

Place the device at a moderate height (about 120–150 cm from the floor) and avoid mounting it directly above the heater or next to water pours. Use the combined temperature and humidity readings together to assess whether the sauna atmosphere is within desired ranges for safety and comfort. If readings appear inconsistent after prolonged exposure, remove the gauge for inspection and allow it to dry before reinstalling.
