Extremely rugged, coated aluminium construction, with heater
Overview
Unlike conventionally shaped rain gauges the SBS500/500H are aerodynamically designed to minimise sampling errors that can occur during wind-driven rain. The deep collector body of the SBS series is also less susceptible to ‘splash-out’ errors. The profile of these gauges follows extensive research by the Institute of Hydrology at Wallingford in the UK, and is very similar to that derived theoretically and independently by the UK Meteorological Office as an ‘ideal’ shape.

Technical Description
The SBS500/500H collector bodies are precisely engineered from powder-coated aluminium, and the base from LM6 marine grade aluminium. They are corrosion free, extremely rugged and provide increased rainfall catch with minimal airflow interference. The SBS500H is a heated version of the gauge.
Recommended installation is by bolting to a concrete base. The SBS500 / SBS500H have a built-in levelling device.
