The SG-410 Cloudburst Heated Weighing Precipitation Gauge is a high-accuracy, all-weather sensor designed to measure rain, snow, sleet, and hail. Featuring a precision stainless steel load cell, heated inlet, and advanced filtering algorithm, it delivers reliable precipitation measurements by compensating for temperature, evaporation, and wind-induced vibration. Its rugged, no-moving-parts design ensures dependable long-term performance, even in harsh winter conditions.
