Class A rain gauge (200 cm²)

The Helmann PL200 rain gauge is a manual rain gauge. It consists of a cylindrical body in anodized aluminium with 200cm² collection surface, that collects rain in a can with a maximin of 3l (corresponds to 150mm) of capacity, or directly in a graduated cylinder in class A or A+, its capacity is 250ml (250cm³) equal to 12.5mm of precipitation (200cm³ ≡ 10mm). The orifice collecting funnel, is designed to convey all the precipitated rain inside the collector and then to be measured using a high precision graduated cylinder (resolution 0.05 mm and 0.04 mm in class A to class A+) able to measure from 0 to 12,5mm.

The shape of the funnel ensures that all the precipitated rain goes in the collector without any loss.
