Product Introduction: This is an excellent product integrating an altimeter, barometer, thermometer, and compass. Made of high-quality materials, it is drop-resistant, pressure-resistant, and resistant to both cold and heat, making it suitable for various harsh environments. The barometric altimeter has a built-in high-sensitivity barometric pressure sensor that measures real-time air pressure at your location. Since altitude is proportional to air pressure, it can be used to measure relative altitude; once the altitude value is correct, it can measure real-time altitude. This four-in-one barometer, altimeter, thermometer, and compass requires no batteries or chargers, and no maintenance or repair. Rugged and durable, requiring no electricity, it is an excellent outdoor tool. The barometric altimeter can predict future weather changes based on air pressure, allowing you to prepare in advance. This barometer is portable and rationally designed, bringing convenience and practicality to your outdoor activities. This barometer essentially combines the functions of an altimeter, compass, and thermometer. It is an environmentally friendly product with a purely mechanical structure, designed specifically for outdoor sports such as mountaineering, rock climbing, and skiing.
