Measurements: 15-3/4"H, overall 1-3/4"L x 8"H, blue tube 2"L x 7-3/4"H, copper holder 3"L, top of copper holder Materials: Iron and plastic Notes: Heat/Cold Resistant Easy to Read / Easy to Use Easy to Insert / Easy to Move Accurate rain gauge: Pay attention to rainfall, care for plant growth, play and share fun. Engineered with Archimedes' buoyancy theorem, this dual-function instrument combines rainwater collection (0-300mm/h) with real-time fluid dynamics visualization. The low-density polypropylene buoyancy tube (0.91 g/cm³) rises proportionally to precipitation volume, translating buoyant displacement into millimeter-accurate measurements through laser-etched blue/white scales. Scientific Validation ▸ Buoyancy-Displacement Algorithm Pre-calibrated standards with 99.2% simulation accuracy.
