70mm Analog Barometer — stainless steel, battery-free precision for reliable atmospheric readings Key benefits Accurate atmospheric pressure readings from a precise mechanical movement — no batteries required, so the instrument works continuously in remote or off-grid locations. High sensitivity technology and bold measurement markers make it easy to detect small pressure changes and read values quickly, helping you anticipate weather shifts. Durable stainless steel construction with scratch-resistant glass protects the dial and ensures long-term performance in outdoor and agricultural environments. What it solves Provides dependable pressure data for local weather forecasting without reliance on power or electronics. Reduces maintenance and downtime compared with battery-powered instruments. Helps users make timely decisions — from adjusting farm activities to planning outdoor routes — by delivering sensitive, easy-to-read pressure information. Key attributes Function: Analog barometer for measuring atmospheric pressure; mechanically driven for consistent, long-term operation. Size: 70mm dial — compact for mounting in tight panels or adding to an existing weather station. Material: Stainless steel case for corrosion resistance; scratch-resistant glass over the dial for protection and clear readability. Performance: High sensitivity movement and bold markers for fast, accurate readings without electronic calibration. Compatibility: Designed for mounting in home weather stations, instrument panels, farm equipment shelters, and other sheltered outdoor installations. Practical use scenarios Home weather station: Add the 70mm analog barometer to a residential weather station to monitor local pressure trends and improve short-term forecasting at a glance. Agriculture and livestock shelters: Install in barns, greenhouses, or farm equipment shelters to track pressure changes that can affect crop conditions, pest activity, or ventilation decisions. Outdoor activities and fieldwork: Use as a compact, battery-free reference to detect relative altitude changes and approaching weather when hiking, camping, or conducting field research. Reliable, low-maintenance performance for anyone who needs straightforward, accurate atmospheric pressure readings without dependence on batteries or electronic systems.
