Foxyoo 4-inch Outdoor Thermometer & Humidity Gauge — Brass Analog Dial, Battery-Free

Foxyoo 4" Outdoor Thermometer & Humidity Gauge is a battery-free brass analog dial that displays both temperature and relative humidity for patios, greenhouses, and home exteriors.

This compact analog weather gauge combines a 4-inch brass-framed dial with dual Fahrenheit/Celsius scales and a 0–100% humidity indicator. Designed for straightforward wall or window mounting, it gives real-time, mechanical readings without batteries or digital maintenance. The retro brass finish doubles as decorative outdoor decor while providing practical environmental feedback to help you care for plants, outdoor gear, or living spaces.

How accurate are the temperature and humidity readings?

The dial shows Fahrenheit (-30°F to 120°F) and Celsius (-30°C to 50°C) with an advertised accuracy of ±4°F (±2°C) for temperature and ±5% for humidity. It’s a mechanical instrument best suited for general monitoring rather than laboratory precision. For most garden, patio, and household uses it provides reliable directional trends and immediate, easy-to-read values.

Where can I mount this gauge and how easy is installation?

Foxyoo supplies two screws and four rubber anchors so you can install the unit on wood, masonry, siding, fence posts, or inside a window frame. The compact 4-inch dial and brass stand make it suitable for small spaces like balconies or greenhouse benches. No wiring or batteries are needed, and basic tools are enough for setup.

How should I care for and position the thermometer for best results?

To protect accuracy and longevity, place the gauge in a ventilated, shaded spot that avoids direct sun, heavy rain, or snow. Regularly wipe the brass face and glass with a soft cloth to remove dust and preserve readability. For outdoor mounting, a covered porch or an eave-protected wall helps reduce weather exposure while still reflecting ambient conditions.

• Avoid direct sunlight and exposure to driving rain or snow
• Clean with a soft cloth to prevent scratches and maintain dial visibility
• Position in a shaded, ventilated area for representative ambient readings
• Indoor use: place away from heat vents or kitchen steam sources

What makes the Foxyoo gauge a good decorative and functional choice?

The brass-trimmed 4-inch dial pairs vintage styling with practical dual-scale readouts, serving as both decor and a monitoring tool. Its analog face is easy to read at a glance, and the metal housing gives a classic accent that complements rustic, farmhouse, or traditional outdoor aesthetics. The lack of electronics means it continues to work through power-free settings and simple lifestyle spaces.

• Retro brass finish fits many outdoor and indoor design schemes
• Dual Fahrenheit and Celsius scales for flexible use
• Analog, battery-free operation for low maintenance
• Small footprint ideal for decorative placement on porches and shelves
