Thermometer‑Barometer — compact aneroid dial instrument that measures air pressure to help you predict short‑term weather changes Key benefits Simple, reliable weather indication: measures atmospheric pressure so you can anticipate weather changes without relying on apps or forecasts. Compact and easy to read: clear pointer (needle) dial shows pressure trends at a glance. Ready for indoor or sheltered outdoor use: designed for home, garden, greenhouse or workshop monitoring. Durable, lightweight construction: made from quality plastic and metal for stable performance and easy mounting. What it does Aneroid barometer function: senses air pressure and displays readings on a mini dial with a pointer to indicate rising, steady or falling pressure. Manual calibration required before use: adjust the brass set screw on the back with a small screwdriver to align the gauge to local reference pressure. Key attributes Type: Thermometer‑Barometer / aneroid barometer with pointer dial (mini dial barometer). Materials: high‑quality plastic housing and metal components for the dial and mechanism. Form factor: compact, mini dial — suitable for mounting on walls or placing on shelves. Operation: mechanical (aneroid); no batteries required. Calibration: adjustable via brass screw on the rear; small screwdriver needed for initial setup and periodic re‑calibration. Performance and compatibility Provides a straightforward, mechanical way to monitor atmospheric pressure and infer near‑term weather trends. Functions well indoors and in sheltered outdoor locations such as covered patios or garden tool sheds (avoid direct exposure to weather elements). Compatible with typical household mounting locations; lightweight design makes it easy to relocate. Use scenarios Garden planning: check pressure trends before planting, watering, or scheduling outdoor projects. Home weather awareness: keep the barometer in living rooms, kitchens or entryways to notice pressure drops that often precede storms. Greenhouse or shed monitoring: monitor pressure changes to support microclimate awareness for plants and stored equipment. How to set up Mount or place the barometer where you want to monitor pressure. Obtain a local reference pressure (from a trusted weather station or online source). Use a small screwdriver to turn the brass screw on the back until the pointer matches the reference reading. Recalibrate periodically or after moving the instrument. What to expect A compact, mechanical barometer that gives quick, visual feedback about atmospheric pressure and short‑term weather tendencies. Robust plastic and metal construction for everyday indoor and sheltered outdoor use. Simple calibration and no battery dependence for low‑maintenance performance. Specifications summary Instrument type: Thermometer‑Barometer (aneroid barometer, pointer dial) Materials: plastic housing, metal dial and mechanism Adjustment: brass screw on rear, requires small screwdriver Intended use: indoor and sheltered outdoor (garden) pressure monitoring Order with confidence if you need a small, mechanical barometer for quick, local weather indication and easy installation.
