Outdoor Rain Gauge and Snow Professional Stratus Long Term, Made of UV and Heat Resistant Polycarbonate Material for All Weather Conditions with Precise Mounting Bracket

Most accurate scientific rain gauge. This is the third one I've owned. I hope they've improved the plastic. Eventually mine have gotten so fogged from sun exposure, you can't see the water level.

Sturdy, well made. Easy to install. Remember, you have to manually empty it which could be a pain in the posterior.

Really like the ease of reading, the snow measurement ability, and its accuracy. Only problem is cleaning out the flies each time that love to gather and die in the bottom.

After a lot of researching for a rain gauge that allows 0.01" resolution for measuring very low rainfall amounts and was UV resistant I came upon this device. The crystal-clear polycarbonate (Lexan) construction should hold up a long time outdoors and shouldn't crack or craze like other plastics that breakdown with long-term exposure to the sun's UV light and heat. The 4 inch diameter opening at the top of the removable funnel collects ten times as much water as the smaller diameter graduated tube inside that stores the rain water so this allows the water level in the small tube inside to easily show hundredths of an inch increments of rainfall. We also wanted a rain gauge that wouldn't have to be mounted on a fence or post so it could be used on a level section of our yard to measure the quantity of water applied to our lawn from our sprinkler. The base is just over 4" in diameter allowing us to sit the rain gauge directly on the ground. I added four rubber feet to allow it to sit on concrete or other rough surface to prevent scratching the plastic and it also prevents slipping on smooth wet surfaces. The ten-inch long small tube has a spill-over notch at the top so if more than one-inch of rain has fallen the water runs over into the outer 4" diameter tube. Remember, one inch of rainfall becomes ten inches of water level in the small tube. So if you had a total of say 2.28 inches of rain, you would empty the water in smaller tube then fill it up to the top from the excess water in the 4" diameter tube. Then empty the smaller tube again (representing a total of 2 inches of rain) and then pour the remaining water from the 4" tube into the smaller tube. The water level should show 0.28 inches which when added to the two inches already accounted for would give the total of 2.28 inches. One of my photos shows the unit sitting on my driveway, another photo shows an engineering scale inside the small tube next to the markings on the smaller tube to show the relationship of the 10 to 1 scale. Another photo show where I applied rubber feet. And the last picture gives a visual explanation of how the 10 to 1 scaling works. Be sure to lift the assembly by the lower 4 inch cylinder and not the top since the top is not secured to the lower 4 inch cylinder and, as it happened to me, the lower 4 inch cylinder will fall off! I wish it had some sort of latching clips or a twist-on/twist-off locking design to prevent this from happening. UPDATE: We finally had some rain after I bought this to do a real-life test. We had 0.915" of rain overnight (almost an inch) and I've added some photos of the results. We had some wind which blew small bits of dead leaves and other plant matter into the collection funnel and made it thru the small opening (about the diameter of a pen or pencil) at the bottom of the funnel and into the small tube. Some of the small debris was floating at the top of the water column and some settled to the bottom of the small tube. I'm thinking of fabricating a fine screen filter to go inside of the funnel top to trap this debris from falling into the small tube. Very impressed with this product and the only improvement I'd like to see is a debris filter added and a twist-lock/unlock design to lock the funnel on top to the 4" tube below.

Overall it is a well made gauge. The funnel top on this new one does not seem to fit as snuggly as the old one I replaced. Being in Florida I'm a little concerned about it staying on in a hurricane.

I’ve had one for years and it has always worked great. I ran in to the previous one with a ranger and had to replace it. The only complaint I have is that my neighbor has one just like it and he always has a few hundredths more than I do.😉

This is a great price for a sophisticated rain gauge. Easy to set up and to read. Highly recommend.

Does not measure snow depth. No inch measure on container for snow. Instructions for snow is to melt it and pour it into the 1 inch measuring tube. Also only measures 1 inch of rain the rest of the water over flows to the larger container with no inch measurements on it. You are suppose to pour it out into the 1 inch tube. There is no spout on the larger container.
