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.

5 stars All Weather Rain Gauge.
I recently joined the CoCoRaHS community. They require the use of an official National Weather Service 4" rain gauge for accurate and uniform measuring of precipitation. After looking at several different online distributors of this specific rain gauge, I decided to order from your company. I chose your company based on the testimonials from other Weather Shack customers and the free shipping on items over $50. I also had contacted your company by phone prior to ordering online to make sure I would be comfortable dealing with your organization. The representative was kind and professional. The rain gauge and the spare measuring tube arrived at my home just three days after I ordered it. It would have been two (2) days if I had ordered by 3:00PM. My thanks to both your company and the USPS for fast and efficient service.

Bought two, one placed down by the water (bay) and one 100-150 feet away by garden. Compared results with my Davis electronic rain gage. Water(bay) gage = 0.815", Garden gage = 0.765", Davis electronic gage = 0.800" All close

5 stars Rain gauge tested on first day
We received the rain gauge just in time for the biggest rain we've had in 4 or 5 years. The ability to clearly measure hundreds of an inch is great, but we were able to test the more than one inch overflow, as well. Excellent product.
