Stratus® Professional Precision Rain Gauge

Track rainfall for gardens, farms, and manual weather stations with the American-made Stratus® Professional Precision Rain Gauge. Its graduated measuring tube helps you record precipitation and build a useful local rainfall history.

Readings for Practical Decisions

The measuring tube has 0.01-inch graduations. Graduation spacing is not a guarantee of field accuracy: placement, reading technique, maintenance, and observation timing all affect the usefulness of your records. Use rainfall observations alongside soil conditions and plant needs when planning irrigation.

CoCoRaHS & Professional Observation

For CoCoRaHS participation, local professional observation, or National Weather Service (NWS) reporting, check the current equipment requirements and observation procedures of your program. Do not assume purchasing a gauge establishes program approval or that every reporting network uses the same requirements.

For a manual weather station, keep consistent observation times and follow the applicable instructions for siting, reading, emptying, and cleaning the gauge. Nearby buildings, trees, and other obstructions can affect precipitation collection.

Rainfall & Winter Observation Guides

Read the rainfall-tracking guide for gardeners and farmers.

Winter precipitation requires a different procedure from reading liquid rain. Follow your observation program’s current instructions for collecting and measuring the liquid equivalent of snow and other frozen precipitation.

Frequently Asked Questions

What does the 0.01-inch marking mean?

It describes the measuring tube’s graduation interval, not guaranteed field accuracy. Correct siting and reading procedures matter.

Can I use Stratus for a reporting program?

Check your CoCoRaHS, NWS, or local observation program’s current equipment and reporting requirements before choosing and installing a gauge.

Is the Stratus rain gauge Made in USA?

Yes. The Stratus® Professional Precision Rain Gauge is manufactured in the United States.

How should I measure winter precipitation?

Follow your observation program’s current collection and liquid-equivalent measurement procedures rather than treating frozen precipitation as a normal rain reading.
