TERMOFLY 10.3" Wall Thermometer — Large Dual-Scale °C/°F, Waterproof Alloy Steel Vintage Analog

TERMOFLY 10.3" wall thermometer is a battery-free analog thermometer with a large, easy-to-read dual-scale dial and a weatherproof steel body for both outdoor and indoor use.

This compact analog thermometer combines vintage styling with practical engineering so you can check temperature at a glance. The oversized numerals and contrasting dial were designed to improve visibility across a patio, kitchen, garage or garden. Built from alloy steel with a waterproof finish, it resists outdoor conditions while delivering Celsius and Fahrenheit readings without needing power.

How easy is it to read from across a room or yard?

The face uses large, bold numbers and a high-contrast pointer to make temperature legible from a distance. This visual clarity helps when you’re checking conditions from indoors to outdoors or from across a patio.

• 10.3" diameter dial with enlarged numerals for quick scanning
• Dual scale (°C and °F) shown clearly on one face
• High-contrast hand and markings for low-light visibility

Will it hold up outside in wet or changing weather?

Yes — the TERMOFLY thermometer uses a corrosion-resistant alloy steel case plus a waterproof finish to stand up against rain, humidity and temperature swings. Its construction is intended for long-term exterior mounting while minimizing maintenance.

• Premium alloy steel housing resists rust and dents
• Waterproof treatment on exterior surfaces for outdoor exposure

Do I need batteries or frequent calibration?

No batteries are required — this is a purely mechanical analog thermometer. It includes an adjustable calibration feature so you can fine-tune readings if needed, and the simple mechanism reduces ongoing maintenance compared with electronic units.

• Mechanical sensing element provides continuous readings without power
• Manual calibration screw to align readings with a reference device
• Stable performance over time when mounted in sheltered positions

How do I install it and where does it fit best?
