This version of the RG1 weighs in at less than half a kilo and is suited for both mast and floor mounting. The measurement is done by a double tipping bucket system that’s factory calibrated to remain within a <2% accuracy in rain falls up to 60mm per hour. The steep angle of the buckets makes water run of quickly and thus prevents the build-up of residue, like sand or dust in the buckets.Water is collected through a funnel with an orifice of 200 cm². Leaves and bird droppings are kept out of it by means of an aluminum filter, that can easily be taken out for cleaning. The funnel attaches to the body with a bayonet-style lock, which prevents the funnel from being shaken off in heavy winds.All parts (except the buckets) are made of aluminum that’s anodized for extra protection and durability.The sensor comes complete with all mast mounting equipment, two pipe clamps, and a shielded 1m cable with a 7-pin Binder jack, compatible to all RTU’s of the A723, A733 and A75x families.
