How much water does a tipping bucket hold?

A tipping bucket rain gauge typically holds a small amount of water, usually around 0.2 to 0.5 milliliters per tip, depending on the design. When a specific volume of water fills the bucket, it tips, triggering a mechanism that records the rainfall. The total capacity of the bucket itself is generally limited to just a few milliliters, as its purpose is to measure rainfall rather than store large quantities of water.
