DUNUO 4-Inch Brass Outdoor Thermometer & Humidity Gauge — Battery-Free, Swivel Mount for Adjustable Viewing

The DUNUO 4-inch long-arm brass outdoor thermometer and humidity gauge is a battery-free, weather-resistant wall or window instrument that displays temperature and relative humidity with a vintage brass swivel mounting for adjustable sightlines.

Designed for patios, porches, greenhouses and garage doors, this compact analog weather instrument combines a classic brass finish with practical readings. It uses mechanical sensors so there are no batteries to replace, and its solid brass swivel bracket lets you angle the dial for easy viewing from different positions. Built to tolerate sun, rain and snow, the unit also offers calibration guidance and modest accuracy tolerances so you can trust its day-to-day measurements.

How accurate are the temperature and humidity readings?

The DUNUO gauge gives reliable everyday readings: temperature with about ±2% tolerance and humidity within ±5%, making it suitable for general monitoring rather than laboratory precision. A simple calibration procedure in the manual helps keep the readings consistent over time.

• Temperature tolerance: approximately ±2% for typical outdoor ranges.
• Humidity tolerance: approximately ±5% relative humidity.
• Includes guidance for periodic calibration to maintain accuracy.
• Mechanical sensing avoids battery drift and electronic failure modes.

Can I mount it on different surfaces and adjust the viewing angle?

Yes — the unit features a solid brass swivel design that mounts on walls or window frames and can be angled for best visibility. The swivel allows you to position the dial to avoid glare, read from multiple approaches, or orient it for decorative effect.

• Solid brass swivel bracket for durable, rust-resistant mounting.
• Works as a window thermometer, wall thermometer, or porch fixture.
• Mounting hardware fits common exterior surfaces like wood and masonry.
• Adjustable angle reduces reflection and improves readability.

Is this thermometer suitable for year-round outdoor use?

Built to withstand typical outdoor conditions, the DUNUO instrument is weather-resistant and can be left outside through changing seasons. Its brass construction tolerates moisture and sunlight better than many lightweight plastics, but best practice is to mount it in a shaded, sheltered spot to extend life and keep readings stable.

• Weather-resistant brass housing resists corrosion from rain and snow.
• Recommended placement: shaded or covered areas for longest life.
• Works well in patios, greenhouses, garages and porches.
• No batteries required—mechanical operation suitable for year-round use.
