Industrial-Grade Optical Rain Gauge RG-9 detects the size of raindrops and provides information on rain intensity to the users. It features easy-installation and maintenance-free, suitable for applications in weather and climate studies, hydrological network monitoring, agriculture, and other scenarios that need monitoring rainfall.

Features:

Industrial-grade: round and reliable lens surface which discourages the collection of debris and dirt
Easy-installation: on weather station masts, buildings, and other infrastructures
Maintenance-free: as a low maintenance rain gauge, it can be used for 7-10 years without replacement
Compacted Sized: as small as a tennis ball
Wide Application Scenarios
