CLIMALYTIC Tropo Rain Gauge & Snow Gauge — 13.5-Inch Capacity, Freeze-Proof, CoCoRaHS-Approved Precision

Meet the CLIMALYTIC Tropo Rain Gauge & Snow Gauge, engineered for extended outdoor use with thoughtful details and professional-grade accuracy. This premium manual gauge blends a compact inner cylinder with a generous outer cylinder, delivering a total capacity of approximately 13.5 inches and a high-resolution reading you can trust in varied conditions.

The Tropo design mirrors NOAA’s official standard for precipitation measurement, using a dual-cylinder system to separate liquid precipitation from frozen forms in a way that supports clear reporting. The inner cylinder holds 1 inch (25 mm) and the outer tube adds up to 12.5 inches (317.5 mm), while the scale provides readings in 0.01 inch (0.25 mm) increments for fine detail across light showers to heavier storms.

CoCoRaHS-Approved status reflects its usefulness for community science projects and personal weather logs. The gauge’s UV-stable, weather-resistant polycarbonate body is designed to endure full sun, rain, and freezing temperatures without fading or hazing. Its modular design includes a removable inner cylinder and funnel top cap to adapt for snow or frozen precipitation, which can be melted or weighed to obtain a liquid equivalent.

Ease of use is a core focus: install with the universal mounting bracket on a post, patio rail, or shed, then remove and re-mount as needed even in cold snaps. A pour spout simplifies decanting outer-tube rainwater, and a dedicated handle helps prevent spills during data collection.

Practical, real-world scenarios include backyard weather tracking, classroom data projects, and community reporting. The Tropo’s versatile features support a straightforward, hands-on measurement process, while safeguarding long-term durability under diverse conditions.
