This rain guage model uses an attractive twisting stake to mount in soft ground OR mounting ring to attach onto a post.  (Both mounting brackets are included)  This measures in 1/10 inch increments in front and 1 millimeter increments on the reverse side.  This rain gauge is very easy to read.  The gauge uses water collected in the convex-shaped glass to magnify the numerals by 50% in width.  It also features a brass screen at the top of the collection funnel to keep out unwanted leaves and bugs.  If post mounted, the length is 8", if mounted in the ground, height is 23"
