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.

I have been looking for a rain gauge of this quality for 20 years. I had friends that had a NWS copper rain gauge that was very precise and durable. This works for a fraction of what the copper gauge cost.

5 stars What an amazing product!
When I bought the rain gauge, I was pretty excited to actually have a professional rain gauge. The shopping process was really simple and easy. Shipping didn't take too long either. I now have the gauge set up and I love it.

4 stars Missing one little thing
I really haven't had a chance to put it up yet, but I found one little thing wrong with it. Around the bottom of the spout where it directs the water into the inner tube there are 4 little fins (?) missing, that should be there to hold that inner measuring tube upright and perpendicular. Without those fins, the inner tube has some play and moves around a little bit and can lean over, as the bottom of the funnel does not come in contact with that tube and doesn't hold the tube in place itself, and so that tube can flop around a little inside the outer can. The water from the funnel will always fall into the measuring tube, but that tube without something else like these fins that hang down from the underside of the funnel, this tube will never sit fully upright all the time. The one I had from the National Weather service had these tabs and held tube in place perfectly.

5 stars Stratus rain gauge
We have had our rain gauge through a couple of rain falls and love how super easy it is to measure the rain fall with such precise accuracy. Mounting directions were easy to follow and very helpful to. I still have some concern with losing the funnel in a wind storm as it doesn't lock in place. I ordered two rain gauges,one for me and the other for my brother. He is satisfied as well. These aren't your average hardware store gauges. These are very well made.

It's nice to have a new one after using the older same kind of rain gauge for many years. It is fine and is very clear to read. Paul

5 stars My mistake
I completely misread the description and thought it measured 11 inches not 1 inch so I can't use the product.
