TB4, TB4MM, CS700, and CS700H
Tipping Bucket Rain Gages
1. Introduction
The TB4, TB4MM, CS700, and CS700H are tipping bucket rain gages that
funnel rain into a mechanism that tips when filled. The TB4, CS700, and
CS700H measure in 0.01-inch increments and the TB4MM measures in
0.2-mm increments. The TB4 and TB4MM have a lightweight plastic base, and
the CS700 and CS700H have a heavy-duty, cast-aluminum base (FIGURE
). The CS700H is a heated rain gage for measuring the water content of
snow.
