Stratus 6330 Rain Gauge Built for Accurate Rainfall

The Stratus 6330 Precision Rain & Snow Gauge is a manual, high-accuracy precipitation measurement instrument designed for both rain and snow collection. It requires no power source — no batteries, wiring, or electronics — making it exceptionally simple and dependable. Water funnels into a clear inner measuring tube that magnifies up to 1 inch (or 25.4 mm) of rainfall in fine increments, after which excess volume overflows into a larger outer cylinder. The transparent design allows for easy reading, while the durable, UV-resistant polycarbonate construction ensures long-lasting performance in all weather. Its capacity goes up to 11 inches (279.4 mm), supporting heavy precipitation events, and can be quickly disassembled to measure snow by removing the funnel and inner tube. The gauge comes with a quick-connect mounting bracket for easy installation on posts or railings. The Stratus 6330 is trusted by professional observers (including NOAA/NWS networks) for its precision.
