The TROPO Precipitation Gauge is the next generation 4-inch all-weather professional precipitation gauge that meets the accuracy and specification requirements of CoCoRaHS. The TROPO is the approved, premium CoCoRaHS gauge option.

The TROPO is the first comprehensive refresh of the 4-inch Stratus All-weather Rain Gauge, which was first introduced way back in 1973! Based on the design of NOAA’s National Weather Service official standard 8” rain gauge, the TROPO Precipitation Gauge uses the same dual cylinder design to measure precipitation with a resolution of 0.01” (.25 mm).

The inner cylinder holds 1 inch (25 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 funnel top 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 UV stabilized Polycarbonate; the same weather resistant material as greenhouses.

This is the most advanced, accurate and easy-to-use manual precipitation gauge available.

Features:

13.5” (342.9 mm) maximum capacity
Textured grips on outer cylinder for secure handling of the gauge
Bird deterrent rods (optional)
Funnel opening atop inner cylinder for easy filling without outer tube cap.
Outer cylinder gradations for quick, estimated readings
Removable handle for easy handling of the unmounted gauge.
Flexible, easy mounting bracket for pole or post installation with weather-protected bracket design for easy mounting & unmounting
Inner cylinder equipped with stabilising base for easy filling
Locking funnel cap to avoid blow-offs
Extra tall cap walls for more accurate catchment of precipitation
Beveled guide on bottom of outer cylinder allows inner cylinder to easily slide in place

Benefits:

Safe, easy operation with textured grips and removable handle
Attain more accurate precipitation measurements with fewer measurement mishaps
Save time cleaning the gauge from bird droppings
Save time and avoid potential damage while dismounting gauge in icy or frozen conditions
Save money by not buying blown off and lost cap/funnel
