Can a rain gauge be cool? Normally, no. But this is the World's Coolest Rain Gauge and it will forever change your mind about the humble pluviometer, an obsolete word for the rain gauge, likely from the French word pluviomètre (Latin pluvia, rain + -mètre, meter).
Admittedly, this rain gauge is a little different than most. The numbers on the measurement tube are in reverse order. The tube doesn't hold water. When it's empty, you can't see the numbers. What's going on here? Does this thing even work?
It certainly does. And there are centuries of science backing it up. The theory behind this pop-up rain gauge is based on Archimedes' principle of water displacement. As water flows into the solid copper collection flute, the measurement tube rises to show water accumulation. To paraphrase the great man himself, "Eureka! That's cool!"
The 9-inch solid copper rain gauge with a metal stand is great for a patio, deck, or a low-growing garden bed. Inside the flute, a blue polycarbonate tube and foam float wait patiently for rain. As rain falls into the collection flute, the blue tube rises to show the accumulated precipitation. Cool, right?
World's Coolest Rain Gauge 9 Inch Copper
Usability - The measurement tube is marked in 1/4 inch increments and measures up to five inches of precipitation.
Visibility - The measurement tube floats up, so you can read it from up to 30 feet away, just by observing how much of the tube is showing!
Durability - The solid copper flute will weather to a graceful patina over time, but it will not rust, rot or crack. The metal stand is powder-coated for rust resistance. The rain gauge passes up using a glass measurement tube in favor of bright blue polycarbonate plastic - it's unbreakable, freezes proof, and will not be damaged in temps below 32 degrees. Of course, if there's rainfall in the tube the precipitation will freeze but not damage the tube. The copper flute has a lifetime manufacturer warranty. The plastic and steel parts have a five-year manufacturer warranty.
