The Model 6331 Plastic Metric Rain Gauge measures up to 280 mm of precipitation and is made of clear, tough butyrate. The internal measuring tube, with a capacity of 25 mm, is graduated to 0.2 mm. Precipitation greater than 28 mm overflows into the outer cylinder and is measured by pouring into the measuring tube. The receiving funnel and measuring tube are removed for collection of snow. A sturdy, rust-proof mounting bracket is included with the gauge.Specifications:
