Optical Rain Gauge RG-9

Rain Gauge RG-15

Product Description

This industrial-grade optical rain gauge is intended to replace conventional tipping buckets rain gauges. It uses beams of infrared light within a plastic lens about the size of a tennis ball. It's maintenance-free; with the round surface of the lens, there are no collections of debris, no moving parts to stick or water-pathways to clog.

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.

Features

  • Industrial-grade: reliable, accurate, and rugged
