Rain Gauge and Rain Sensor Comprehensive Industry Wide Directory
/Rain Gauge and Precipitation Sensor Directory
This page is an attempt at a comprehensive directory of rain gauges and precipitation sensors from manufacturers around the world. The tables list instrument characteristics only, not ranking calculations. If you know of a missing rain gauge or a correction, please leave a comment at the bottom of this page.
Tables are grouped by measurement type and alphabetized within each group. This directory intentionally omits calculated ranking metrics and threshold values.
