Overview

The RK900-10 Automatic Weather Instrument is an advanced all-in-one weather monitoring solution engineered to provide comprehensive atmospheric data in a single integrated device. It utilizes ultrasonic technology for wind measurement, eliminating mechanical wear and ensuring long-term reliability. The system incorporates MEMS-based sensors for temperature, humidity, and pressure, while a 24GHz radar module enables precise rainfall detection and intensity measurement.

This weather instrument is designed for both stationary and mobile applications. With optional GPS and electronic compass modules, it can determine location, movement, and calculate real-time wind vectors, making it especially suitable for use on vehicles, ships, and other moving platforms. Its rugged construction, IP66 protection rating, and built-in heating function allow it to operate reliably in harsh environmental conditions.

The RK900-10 supports multiple communication protocols such as RS485, RS232, and SDI-12, enabling seamless integration with monitoring systems and data loggers. Its modular design allows users to customize measurement parameters according to specific project requirements, making it a flexible solution for meteorological monitoring, renewable energy systems, smart agriculture, and environmental research.
