Easily and accurately monitor rainfall amounts with the Productive Alternatives Stratus Professional Rain Gauge, a precision weather instrument manufactured to United States National Weather Service and Environment Canada specifications, and is used as its official gauge around the world. Professional and amateur weather observers rely on these standards for accurate rainfall reporting. Constructed of heavy-duty, UV resistant polycarbonate, the Stratus rain gauge will stand up to years of rough weather and full sun without fading or corroding.

Available with either English or Metric measurement increments (Note: Only Imperial units are shown on image. If Metric version is purchased, product shipped is Metric). A funnel top on the rain gauge catches rain and delivers it to the inner measuring tube, while the extra-large outer cylinder captures rain volumes over one inch (25 millimeters) up to 11 inches (300 millimeters), and can be detached to measure snow, hail, or sleet. The Stratus rain gauge is guaranteed accurate to 1/100th of an inch (2/10th of a millimeter)! Clear plastic construction provides a see-through design so the gauge is very easy to read. Installing the rain gauge on a post (away from buildings and trees) is easy with its exclusive "Quick Connect" bracket, which lets you quickly remove the cylinder for easy measurement or cleaning (and there are no metal parts to rust!). Includes rain gauge (funnel, inner measuring tube and overflow tube), post mounting bracket and hardware, one-year daily precipitation log, and detailed instructions.

This is the offical rain gauge for CoCoRaHS, a grassroots volunteer network of backyard weather observers working together to measure and map precipitation (rain, hail and snow) in their local communities. CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network. By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, their aim is to provide the highest quality data for natural resource, education and research applications. CoCoRaHS is now the largest provider of daily precipitation observations in the country. Please click Information about CoCoRaHS to learn more.

It's easy to join, takes only five minutes a day and is a fun way to learn about this wonderful natural resource that falls from the sky. The only requirements to join are an enthusiasm for watching and reporting weather conditions and a desire to learn more about how weather can affect and impact our lives. How often have you seen it rain in your neighborhood and a few blocks away not a drop has fallen? Participating in this program will provide an ever clearer picture of the amount of precipitation that falls in our backyards.

And would be better with inch marks on the outer tube, and a better cup to hold the inner tube. Crazy accurate............

5 stars Accuracy of rain gauge
This is one of the most accurate rain/snow gauges, at a reasonable price, on the market. I am director of Blue Hill Obs. in MA and I attest to it's accuracy.

5 stars Excellent product
I spent a career of 34 years as a hydrologist with the US Forest Service, retiring to Arizona. A neighbor has this same product. I liked the design. The afternoon after I installed the gauge we had a violent rainstorm. The gauge registered 1.07 inches. Very professional, fine product. I look forward to years of accurate service.

5 stars Best low tech rain guage!
I was looking for a non-electronic rain guage that would hold a lot of rain (we've had a very wet early 2017 in NE). This gauge hold a lot of water, and allows very accurate readings of rainfall received. It's a nice piece of equipment!

Owned one years ago, but it became sun scorched so we felt we deserved a new one. Wish it would fill up.

Excellent, sturdy, accurate rain gauge. Best buy.

5 stars Rain Gauge
It's easily mounted on the bracket obtained with the same model ~12 yrs ago and is easy to read. The outer cylinder of the old one became so VERY aged by the sun (I think) that you couldn't estimate the accumulated rain thru it.
