Description

Approved as the "Premium CoCoRaHS Gauge", the TROPO by Climalytic Instruments is a 4-inch diameter, all-weather, professional rain and snow gauge.

Inspired by the original Stratus Rain Gauge, and based on NOAA’s National Weather Service official standard 8” rain gauge (SRG), the TROPO Precipitation Gauge uses the same dual cylinder design to measure rain and snow water equivalent (SWE) to the nearest hundredth of an inch (0.01 in) or fifth of a millimeter (0.2 mm).

The inner cylinder holds 1 inch (25.4 mm) of precipitation, while the extra-large outer cylinder holds another 12.50 inches (317.5 mm) of precipitation making the maximum capacity approximately 13.5” (343 mm). The inner cylinder and locking funnel cap are removable to allow catchment of snowfall or other frozen precipitation, which can then be melted down or weighed to determine a liquid equivalent.

The gauge is made of a premium UV stabilized polycarbonate — the same weather-resistant material used to build greenhouses. The TROPO is freeze-resistant if regularly maintained, emptied, and cleaned.

Climalytic Instruments, our Colorado-based small family business, has taken great effort to improve upon legacy rain gauge alternatives. We've collaborated with CoCoRaHS and independent field testers every step of the way to make the TROPO the most accessible professional precipitation gauge on the market.

    "I expect TROPO will be the premier manual rain gauge for years to come."

    Review by Ric W. (New Hampshire CoCoRaHS Observer)

    From careful measurements by weight it is clear that TROPO is more accurate than similar 4" rain gauges on the market. The longer inner tube is easy to read. I expect TROPO will be the premier manual rain gauge for years to come.

    "Sleek design, highly accurate, easy to mount, and simple to use."

    Review by Cheryl J. - Southwestern OR (NWS Spotter and CoCoRaHS daily reporter)

    Sleek design, highly accurate, easy to mount, and simple to use. Some highlights that will not disappoint: Easy slide on/slide off secure/sturdy mounting bracket, convenient pour spout on the large tube and a brilliantly designed handle that slides onto the outer tube's mounting bracket to pour off your precip in excess of 1" into the inner tube. As a beta tester, I feel privileged to evaluate this excellently designed rain gauge and provide feedback to make it a better product for a wider audience.
