Stratus Professional Weather Rain Gauge with 0.25mm Accuracy

⛈️ Summer Storm Season Is Here — Know Exactly How Much Rain FellStratus® Precision Rain Gauge — 0.25mm Accuracy | CoCoRaHS Official | Made in USAThe Stratus® is the official rain gauge of the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) — the largest volunteer weather observer network in North America, endorsed by NOAA. This metric version measures to 0.25mm precision — ideal for international users, metric-standard weather stations, and observers who report in millimeters. When accuracy matters for irrigation scheduling, garden planning, or contributing to real weather science, this is the gauge serious observers trust.Clear graduated tube with funnel top design maximizes rain collection. Weather-resistant construction built for year-round outdoor use. Made in USA. Why 0.25mm accuracy matters: A standard decorative gauge estimates to the nearest millimeter or more. The Stratus reads to 0.25mm — the precision level required by CoCoRaHS and used by NOAA-endorsed observers worldwide. For irrigation scheduling, that precision changes whether you water today or skip it.Key Specifications Accuracy: 0.25mm precision (metric) Design: Clear graduated inner tube with wide-mouth funnel top Construction: Weather-resistant, UV-stable plastic Certification: Official CoCoRaHS gauge — NOAA observer network Origin: Made in USA Use: Outdoor rainfall measurement for gardens, farms, and weather stations Key Benefits CoCoRaHS Official Gauge — The gauge NOAA-endorsed volunteer observers use nationwide 0.25mm Metric Precision — Ideal for metric-standard weather stations and international users Easy-to-Read Graduated Scale — Clear markings for quick, accurate readings at a glance Wide-Mouth Funnel Top — Maximizes rain collection surface for accurate measurement Weather-Resistant — Built to withstand outdoor conditions season after season Made in USA — Quality American manufacturing Professional vs. Decorative: What's the Difference? Feature Decorative / Digital Gauge Stratus® Precision Gauge Accuracy 1mm or estimated 0.25mm precision CoCoRaHS approved No Yes — official gauge NOAA observer use No Yes Funnel collection design Rarely Yes — maximizes accuracy Made in USA Rarely Yes Battery required Often No — passive, always on How to Read a Rain Gauge AccuratelyReading a rain gauge correctly matters as much as the gauge itself. The most common mistakes: reading at an angle (parallax error), not emptying after each rain event, and placing the gauge too close to trees or structures. The Stratus® graduated tube is designed to minimize parallax error — read at eye level with the bottom of the meniscus (the curved water surface) for the most accurate result.Most vegetables need 25–50mm of water per week. Knowing your exact rainfall total tells you exactly how much supplemental irrigation your garden needs — no guessing.Perfect For CoCoRaHS volunteer weather observers using metric reporting International users and metric-standard weather stations Home gardeners tracking rainfall for irrigation scheduling Farmers and market gardeners monitoring field conditions Backyard weather station enthusiasts Schools and educational weather monitoring programs Frequently Asked QuestionsWhat is the most accurate metric rain gauge for home use? The Stratus® 0.25mm Precision Rain Gauge is the official CoCoRaHS gauge in metric format — trusted by NOAA-endorsed observers and the most accurate manual metric rain gauge available for home and garden use.Is the Stratus rain gauge CoCoRaHS approved? Yes. The Stratus® is the official gauge of the CoCoRaHS network — the largest volunteer precipitation monitoring network in North America, supported by NOAA.How do I read a rain gauge accurately? Place the gauge in an open area away from trees and structures. After a rain event, read the water level at eye level, measuring from the bottom of the meniscus (the curved water surface). Empty the gauge after each reading.How is the Stratus different from a digital rain gauge? Digital gauges require batteries, can malfunction in extreme temperatures, and often measure in coarser increments. The Stratus is passive (no batteries), reads to 0.25mm precision, and never loses data during a power outage or battery failure.Learn More How to Read a Rain Gauge Accurately — Tom's Step-by-Step Guide Stratus vs. Standard Rain Gauges — What's the Difference?
