The CS705 is a snowfall adapter that converts a standard 8 in. tipping bucket rain gage to a year-round rain and snow gage. It is typically used with our TE525WS rain gages. The CS705 consists of the following: One black catch tube One reservoir One overflow (measurement) tube One 14807 drain funnel Two stainless-steel band clamps One set of CM270 mounting hardware Solid precipitation is gathered in the catch tube and mixed with a non-toxic propylene glycol and ethanol (PGE) solution inside the reservoir. The PGE solution lowers the melting point of the frozen snow and allows the resulting liquid solution to flow through the overflow tube and be measured with a standard 8 in. rain gage.
