Product advantages
Cutting-edge technology for precipitation detection
LAMBRECHT meteo, an AEM brand, is a leading global supplier of sensors for precipitation measurement and precipitation detection.
Time-critical and water management tasks
Measuring precipitation is a complex and important task for water management and public safety. In times of climate change, monitoring and measuring precipitation is more important than ever, especially as floods and severe storms are increasing worldwide. Each type of precipitation—rain, snow, freezing rain, or hail—poses unique challenges for measurement.
Our real-time integrated system handles measurement and data collection with minimal effort, allowing you to respond as quickly as possible to flood events or road condition reports.
Consistently reliable and universal
- Fast, secure, easy to install, and maintenance-free
- Reliable detection of precipitation types using radar technology
- Universally applicable with all common data loggers and data acquisition systems
- Monitors emerging disasters to speed up your response
