The RG-9 Optical Rain Gauge is an industrial-grade sensor that detects raindrop size and intensity using optical technology. It installs easily, requires no maintenance, and is suitable for weather monitoring, hydrology, agriculture, and other rainfall measurement applications.
The Industrial-Grade Optical Rain Gauge RG-9 sensor detects the size of raindrops and provides information on rain intensity to the users.
It features easy-installation and is maintenance-free, suitable for applications in weather and climate studies, hydrological network monitoring, agriculture, and other scenarios that need monitoring rainfall.
RG-9 Solid State Rain Sensor features an open-collector output that emulates a conventional tipping bucket, as well as RS232 serial communications that provide more detailed data allowing for configuration of the device.
It can be configured through the serial port, or optionally via DIP switches. A built-in mounting arm allows for convenient mounting to weather station masts, buildings, and other infrastructure. It’s also suitable for solar-powered applications.
